1.1Background of Study
The development of tall buildings has been prolonged in major cities of Malaysia such as Kuala Lumpur, Penang and Johor Bahru due to the rapid growth of urban population ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.2495/SDP160071”, “author” : { “dropping-particle” : “”, “family” : “Fadzil”, “given” : “S F Syed”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “2016” }, “page” : “77-86”, “title” : “Daylight distribution patterns in light wells in residential buildings in Penang , Malaysia”, “type” : “article-journal”, “volume” : “210” }, “uris” : “http://www.mendeley.com/documents/?uuid=ebdaff31-89fd-4ff1-8794-9c33c3e7a972” } , “mendeley” : { “formattedCitation” : “(Fadzil, 2016)”, “plainTextFormattedCitation” : “(Fadzil, 2016)”, “previouslyFormattedCitation” : “(Fadzil, 2016)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Fadzil, 2016). The structural stability of tall building is not only depended on the ability to withstand axial load, but also the lateral performance. Besides, the city such as Penang, due to the geographical location which is an island, it is frequently exposed to wind along the years ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “The recent freak storm incident in Penang, Malaysia has caused damages to the facilities, uprooted trees and causing death. The aim of this study is to estimate the maximum wind speed at the highest level of a high-rise building that has caused the lightning arrestor to drop off and crashed. The wind speed data were collected from four meteorology stations located in Bayan Lepas, Butterworth, Alor Setar and Langkawi. GIS software was used to analyze, estimate and map the wind speed by applying surface interpolation. The interpolation process was conducted by applying the Inverse Distance Weighted (IDW) and Triangulated Irregular Network (TIN) method which are the functions in GIS software namely, IDRISI SELVA. From the plotted wind speed it shows that the result from IDW and TIN are 16.46 m/s and 16.43 m/s respectively. Surface interpolation method was used to estimate the maximum wind speed at 10 m height. By using the power law equation, the estimation of maximum wind speed at Tower A (145.6 m) was conducted and indicates the value of 29.85 m/s and 29.79 m/s. Thus, estimation of maximum wind speed can be approached to determine the value at certain location using these two methods; IDW and TIN and conventional power law method was used to find the value of wind speed at certain height.”, “author” : { “dropping-particle” : “”, “family” : “Deraman”, “given” : “Che”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Chik”, “given” : “Wan”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “Advances in Civil, Environmental, and Materials Research (ACEM14)”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2014” }, “title” : “Case Study: Wind Speed Estimation of Wind Storm Damage in Penang Using Surface Interpolation Method and Wind Speed Profiling”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=daeedca1-c424-4bca-9059-8558681215ae” } , “mendeley” : { “formattedCitation” : “(Deraman & Chik, 2014)”, “plainTextFormattedCitation” : “(Deraman & Chik, 2014)”, “previouslyFormattedCitation” : “(Deraman & Chik, 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Deraman & Chik, 2014). Thus, the impact of wind acting on tall building becomes an important aspect and challenge in structural design.
Nowadays, shear wall is the most common structural element to maintain lateral performance of high rise building in Malaysia. They are flexural members and which normally constructed in high rise buildings to avoid the total collapse of the high rise buildings under lateral loading. The high in-plane stiffness and strength of shear wall are used to resist large horizontal loads and support gravity loads simultaneously. However, the shear wall still have the limitation on building space and opening of window and door ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “Executions of the shear walls along the exterior perimeter of slender high rise buildings enhance the efficiency of such buildings to resist the seismic forces. But uncertainties in the locations of shear walls are very high because of the demandable architectural openings (windows u2013 doors) in the exterior views of such buildings. So, this study presents a considerable interest in establishing design guide lines for numerical investigation of seismic response of shear walls taking into account such openings and their locations. Five three dimensional models of different configurations of the openings are chosen and compared to figure out the best installation of openings having more efficiency on the performance of shear walls under earthquake excitation. Computer generated models are analyzed by SAP2000 program11 and the loading is considered using acceleration time history with a peak ground acceleration 0.25g provided in the new Egyptian code (ECOL2008)13 for seismic loads on structures and building works. The comparative results showed that the top displacement, base shears and stress distributions around the openings depend on the openings arrangement system. The results of staggered opening system in the shear walls (spatial arrangement) are very much close to those resulted in the shear walls without openings than the other opening arrangement cases. Finally the staggered arrangement of openings between the stories in shear walls are suggested to be applied in engineering practice since it satisfies both the architectural and seismic requirements.”, “author” : { “dropping-particle” : “”, “family” : “Abd-El-Rahim”, “given” : “Hamdy H A”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Farghaly”, “given” : “Ahmed Abdelraheem”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “Journal of Engineering Sciences, Assiut University”, “id” : “ITEM-1”, “issue” : “2”, “issued” : { “date-parts” : “2010” }, “page” : “421-435”, “title” : “Influence of Requisite Architectural Openings on Shear Walls Efficiency”, “type” : “article-journal”, “volume” : “38” }, “uris” : “http://www.mendeley.com/documents/?uuid=c40a0d51-3816-42a7-b379-a063f4fdd85c” } , “mendeley” : { “formattedCitation” : “(Abd-El-Rahim & Farghaly, 2010)”, “plainTextFormattedCitation” : “(Abd-El-Rahim & Farghaly, 2010)”, “previouslyFormattedCitation” : “(Abd-El-Rahim & Farghaly, 2010)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Abd-El-Rahim & Farghaly, 2010).
Therefore, a new innovative structure element known as space shear wall, which is a space frame system, to resist the lateral forces generated by the wind activities. The space shear wall will able to maintain the lateral performance while giving advantage such as providing ability of allowing natural lighting ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.6088/ijcser.201304010021”, “author” : { “dropping-particle” : “”, “family” : “Bayat”, “given” : “Behzad”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Ghazali”, “given” : “Mohd Zulkifli M”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Tahir”, “given” : “Mahmood”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “2”, “issued” : { “date-parts” : “2014” }, “page” : “203-214”, “title” : “Space shear wall as an innovative seismic resistant system for structures”, “type” : “article-journal”, “volume” : “3” }, “uris” : “http://www.mendeley.com/documents/?uuid=57bae9a2-7783-4210-8e68-836501b0a3b8” } , “mendeley” : { “formattedCitation” : “(Bayat, Ghazali, & Tahir, 2014)”, “plainTextFormattedCitation” : “(Bayat, Ghazali, & Tahir, 2014)”, “previouslyFormattedCitation” : “(Bayat, Ghazali, & Tahir, 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Bayat, Ghazali, & Tahir, 2014).

1.2Problem Statement
The rapid growth of urban population and increased income in the Southeast Asia has prolonged the development of tall buildings which are either used for residential or commercial purposes ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.2495/SDP160071”, “author” : { “dropping-particle” : “”, “family” : “Fadzil”, “given” : “S F Syed”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “2016” }, “page” : “77-86”, “title” : “Daylight distribution patterns in light wells in residential buildings in Penang , Malaysia”, “type” : “article-journal”, “volume” : “210” }, “uris” : “http://www.mendeley.com/documents/?uuid=ebdaff31-89fd-4ff1-8794-9c33c3e7a972” } , “mendeley” : { “formattedCitation” : “(Fadzil, 2016)”, “plainTextFormattedCitation” : “(Fadzil, 2016)”, “previouslyFormattedCitation” : “(Fadzil, 2016)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Fadzil, 2016). In Penang, there is a higher proportion of new high-rise buildings are going to develop in coming years ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Lim”, “given” : “Kim Hwa”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “1”, “issued” : { “date-parts” : “2015” }, “title” : “Penang Economic Indicators Penang Economic Outlook 2015”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=d1e7c5cb-bf3a-4e15-8003-69fa855ad2cf” } , “mendeley” : { “formattedCitation” : “(Lim, 2015)”, “plainTextFormattedCitation” : “(Lim, 2015)”, “previouslyFormattedCitation” : “(Lim, 2015)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Lim, 2015). Besides that, Penang is also a city that exposed to wind frequently along the years. The average wind speed of building in Penang is about 29.79 m/s ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “The recent freak storm incident in Penang, Malaysia has caused damages to the facilities, uprooted trees and causing death.

The impact of wind acting on tall building becomes an important aspect in structural design.

Shear wall is the most common structural element to maintain lateral performance of high rise building in Malaysia. However, the application of shear walls limited the demandable of architectural openings (windows & doors) in the exterior views of such buildings ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “Executions of the shear walls along the exterior perimeter of slender high rise buildings enhance the efficiency of such buildings to resist the seismic forces.

The shear wall occupied more space in a building and obstructed natural lighting. Besides, with the trend of development of high rise in Malaysia, the main challenge for structural engineers nowadays is to optimise the performance and construction cost for creating an excellent lateral system ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.6088/ijcser.201304010021”, “author” : { “dropping-particle” : “”, “family” : “Bayat”, “given” : “Behzad”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Ghazali”, “given” : “Mohd Zulkifli M”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Tahir”, “given” : “Mahmood”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “2”, “issued” : { “date-parts” : “2014” }, “page” : “203-214”, “title” : “Space shear wall as an innovative seismic resistant system for structures”, “type” : “article-journal”, “volume” : “3” }, “uris” : “http://www.mendeley.com/documents/?uuid=57bae9a2-7783-4210-8e68-836501b0a3b8” } , “mendeley” : { “formattedCitation” : “(Bayat et al., 2014)”, “plainTextFormattedCitation” : “(Bayat et al., 2014)”, “previouslyFormattedCitation” : “(Bayat et al., 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Bayat et al., 2014). The innovation of advanced systems such as mass tuned damper can help to dissipate lateral load but these systems require high production cost to implement. Therefore, this research introduces space shear wall, which is a space frame system, which allow more natural lighting and space, while also strengthen the lateral resisting performance without costing too much has been introduced.

1.3Objectives
The objectives of this study are:

1.4Scope of Study
In this research, the behaviour of a structure is studied based on the lateral performance when exposed to wind loading. The study of wind loading is based on Penang location only. It focussed on the stiffness of structure and distribution of loading to increase the stability of a structure. The application of space shear wall is studied for its properties to resist lateral loading.
The structures of this study are 16 storeys height of building. The structure with shear wall is the control specimen. Another several structures with different configuration of space shear wall are going to study. The parameters of these studies is the lateral displacement of the structure. For wind tunnel testing, models will be tested by measuring its displacement against wind load applied.

1.5Significant of Study

The application of space shear wall is significant in future construction field. Space shear wall is not only has stiffness and high damping to dissipate lateral energy, it also provide the odds to compatible with architectural consideration and encouragement of natural lighting ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.6088/ijcser.201304010021”, “author” : { “dropping-particle” : “”, “family” : “Bayat”, “given” : “Behzad”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Ghazali”, “given” : “Mohd Zulkifli M”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Tahir”, “given” : “Mahmood”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “2”, “issued” : { “date-parts” : “2014” }, “page” : “203-214”, “title” : “Space shear wall as an innovative seismic resistant system for structures”, “type” : “article-journal”, “volume” : “3” }, “uris” : “http://www.mendeley.com/documents/?uuid=57bae9a2-7783-4210-8e68-836501b0a3b8” } , “mendeley” : { “formattedCitation” : “(Bayat et al., 2014)”, “plainTextFormattedCitation” : “(Bayat et al., 2014)”, “previouslyFormattedCitation” : “(Bayat et al., 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Bayat et al., 2014). Besides, it is not only applicable in new development of high rise building, but also able to retrofit existing building when more lateral resisting capacity needed.

2.2High Rise Building
A ‘tall building’ is defined as a multi-story structure in which most occupants reach their destinations on higher floor depend on elevators (lifts) ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Craighead”, “given” : “Geoff”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “chapter-number” : “1 High-Ris”, “container-title” : “High Rise Security and Fire Life Safety”, “id” : “ITEM-1”, “issue” : “August 2005”, “issued” : { “date-parts” : “2009” }, “page” : “1-26”, “publisher” : “Elsevier”, “title” : “High-Rise Building Definition, Development, and Use”, “type” : “chapter” }, “uris” : “http://www.mendeley.com/documents/?uuid=af22312e-4829-4ac1-856e-27e5ce305d22” } , “mendeley” : { “formattedCitation” : “(Craighead, 2009)”, “plainTextFormattedCitation” : “(Craighead, 2009)”, “previouslyFormattedCitation” : “(Craighead, 2009)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Craighead, 2009). This tall building can be categorized as low, mid, high and super high rise (skyscraper). The low rise building is defined as less than four stories, mid rise is considering from five up to fifteen stories, while high rise is ranging from sixteen to fifty and more than fifty stories is the skyscraper ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.2495/SDP160071”, “author” : { “dropping-particle” : “”, “family” : “Fadzil”, “given” : “S F Syed”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “2016” }, “page” : “77-86”, “title” : “Daylight distribution patterns in light wells in residential buildings in Penang , Malaysia”, “type” : “article-journal”, “volume” : “210” }, “uris” : “http://www.mendeley.com/documents/?uuid=ebdaff31-89fd-4ff1-8794-9c33c3e7a972” } , “mendeley” : { “formattedCitation” : “(Fadzil, 2016)”, “plainTextFormattedCitation” : “(Fadzil, 2016)”, “previouslyFormattedCitation” : “(Fadzil, 2016)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Fadzil, 2016).

Besides, The National Fire Protection Association (NFPA) defined a high-rise building as a building taller than 75 ft (23 meters) in height measured from the lowest level of fire department vehicle access to the floor of the highest occupiable storey ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “This research investigated the effects of escape route design and specification, and time taken on evacuation process in high-rise residential buildings in Malaysia. The aim is to produce a fire safety model on how fire safety standards in high-rise residential buildings can be achieved by investigating the relationship between human behaviour and structural design, particularly escape route design and specification. In Malaysia, research on fire safety is very new, particularly research on provision of fire safety in high-rise residential buildings. The number of fire cases involved residential buildings is significantly high compared to other building types. Thus, escape routes in high-rise residential buildings should be designed and constructed to enable the occupants to evacuate the building as soon as fire has been detected. Mixed methodologies i.e. quantitative and qualitative methods were adopted in this research. There are three research methods adopted i.e. observation, simulation and questionnaire. Observations were carried out to identify any problems encountered and to develop the study models for further analysis. Investigations of the effects of escape route design and specification on evacuation process were carried out using specialist software, i.e. Simulex, which simulates the evacuation of people from the building. The aim is to study escape route specifications i.e. staircase, fire door and corridor. Questionnaire surveys were than carried out to investigate the occupantu2019s characteristics, behaviours, perceptions and motivation factors to evacuate the building. From this research, fire safety models proposed for high-rise residential buildings as follows, (1) Fire safety model to achieve fire safety standard in high-rise residential buildings, (2) Escape route designs and specifications, and, (3) Human behaviour model. There are five fire safety components that need to be enhanced i.e. (1) Fire Safety Awareness, (2) Fire Safety Design, (3) Fire Safety Equipments and Evacuation Skill, (4) Fire Safety Audit, and (5) Fire Safety Enforcement. Besides, there are four factors which highly influence the evacuation process, fire and casualty risk i.e.: (1) People behaviour u2013 knowledge and experience, (2) building element and escape routes design, (3) active fire protection system, and (4) legislation and enforcement.”, “author” : { “dropping-particle” : “”, “family” : “Mohamad Yatim”, “given” : “Yahya”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “June”, “issued” : { “date-parts” : “2009” }, “page” : “312”, “title” : “Fire Safety Models for High-Rise Residential Buildings in Malaysia”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=88ef9fc7-d730-4052-a6ad-e613df6e3d59” } , “mendeley” : { “formattedCitation” : “(Mohamad Yatim, 2009)”, “plainTextFormattedCitation” : “(Mohamad Yatim, 2009)”, “previouslyFormattedCitation” : “(Mohamad Yatim, 2009)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Mohamad Yatim, 2009). Another opinion says a high-rise structure is one that extends higher than the maximum reach of available fire-fighting equipment and it is between 75 ft and 100 ft (23 meters to 31 meters) ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Craighead”, “given” : “Geoff”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “chapter-number” : “1 High-Ris”, “container-title” : “High Rise Security and Fire Life Safety”, “id” : “ITEM-1”, “issue” : “August 2005”, “issued” : { “date-parts” : “2009” }, “page” : “1-26”, “publisher” : “Elsevier”, “title” : “High-Rise Building Definition, Development, and Use”, “type” : “chapter” }, “uris” : “http://www.mendeley.com/documents/?uuid=af22312e-4829-4ac1-856e-27e5ce305d22” } , “mendeley” : { “formattedCitation” : “(Craighead, 2009)”, “plainTextFormattedCitation” : “(Craighead, 2009)”, “previouslyFormattedCitation” : “(Craighead, 2009)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Craighead, 2009).
The overall slenderness of a high rise building is defined by its “height-to-base ratio”, being the height of the building divided by its narrowest plan dimension. Basically, higher height-to-base ratios and lower natural frequencies increase the dynamic component of the response to wind. A building with a height-to-base ratio of more than around 5 is expected to respond to wind loads in a significantly dynamic way (where building inertial effects are significant) ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “ISBN” : “9780994152008”, “author” : { “dropping-particle” : “”, “family” : “Kayvani”, “given” : “K”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “23rd Australasian Conference on the Mechanics of Structures and Materials (ACMSM23)”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2014” }, “page” : “15-20”, “title” : “Design of high-rise buildings : past , present and future”, “type” : “article-journal”, “volume” : “I” }, “uris” : “http://www.mendeley.com/documents/?uuid=83729ac0-b420-45d9-93ba-28e763476c61” } , “mendeley” : { “formattedCitation” : “(Kayvani, 2014)”, “plainTextFormattedCitation” : “(Kayvani, 2014)”, “previouslyFormattedCitation” : “(Kayvani, 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Kayvani, 2014).

In fact, New York’s most advanced towers are defined not by their height but by their width or rather, their slenderness. The slenderness ratio is defined as the ratio between a building’s height and its smallest width. For example, a 1,000ft (310m) height of tower that has 100ft (31m) at its narrowest width would have a slenderness ratio of 10:1. “The slenderness of a building is maybe more important than anything else,” said by Silvian Marcus, director of building structures at WSP USA ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “cc-by-nd”, “author” : { “dropping-particle” : “”, “family” : “Runaghan”, “given” : “Paul”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “WSP Group”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2014” }, “page” : “05-07”, “title” : “High-Rise Solutions – High Society: What Tall Buildings Mean For Cities”, “type” : “article-newspaper” }, “uris” : “http://www.mendeley.com/documents/?uuid=cda8e3e8-ed1c-4c39-8ffc-20b00a4764ee” } , “mendeley” : { “formattedCitation” : “(Runaghan, 2014)”, “plainTextFormattedCitation” : “(Runaghan, 2014)”, “previouslyFormattedCitation” : “(Runaghan, 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Runaghan, 2014). In New York’s building code, designs for buildings over 600ft (183m) and any building with a slenderness ratio above 7:1 must be peer reviewed by another engineering practice ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “cc-by-nd”, “author” : { “dropping-particle” : “”, “family” : “Runaghan”, “given” : “Paul”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “WSP Group”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2014” }, “page” : “05-07”, “title” : “High-Rise Solutions – High Society: What Tall Buildings Mean For Cities”, “type” : “article-newspaper” }, “uris” : “http://www.mendeley.com/documents/?uuid=cda8e3e8-ed1c-4c39-8ffc-20b00a4764ee” } , “mendeley” : { “formattedCitation” : “(Runaghan, 2014)”, “plainTextFormattedCitation” : “(Runaghan, 2014)”, “previouslyFormattedCitation” : “(Runaghan, 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Runaghan, 2014).

Therefore, the issue of slenderness must also be considered. A measure of a building’s slenderness is the aspect ratio. For core wall only lateral systems, ratios typically range from 10:1 to 13:1. For lateral systems that engage exterior elements, an aspect ratio up to 8:1 is feasible. Pushing this ratio up to 10:1 can result in the need for special damping devices to mitigate excessive motion perception ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Zils”, “given” : “John”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Viise”, “given” : “John”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “Structure Magazine”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2013” }, “page” : “12-16”, “title” : “An Introduction to High-Rise Design”, “type” : “article-magazine” }, “uris” : “http://www.mendeley.com/documents/?uuid=d55ac7f9-bd1d-4c5f-83c9-542f800e81e5” } , “mendeley” : { “formattedCitation” : “(Zils & Viise, 2013)”, “plainTextFormattedCitation” : “(Zils & Viise, 2013)”, “previouslyFormattedCitation” : “(Zils & Viise, 2013)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Zils & Viise, 2013). The space shear wall system is considered as exterior lateral element, due to the consideration of authenticity in real construction, the ratio used in this research is 4:1.

2.2.1 Demand of High Rise Building
Nowadays, due to the increasing of population in urban areas in Malaysia such as Penang, Kuala Lumpur, Selangor and Johor Bahru, demand for housing is increasing and development of high-rise residential schemes is accelerated in these high-density areas due to scarcity of land for development of landed residential properties ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Tiun”, “given” : “Ling Ta”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “2nd Naprec Conference, Inspen”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2009” }, “page” : “1-25”, “title” : “Managing High-Rise Residential Building in Malaysia: Where Are We?”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=2880d3e8-caa0-428b-a2d7-1166ee2cf189” } , “mendeley” : { “formattedCitation” : “(Tiun, 2009)”, “plainTextFormattedCitation” : “(Tiun, 2009)”, “previouslyFormattedCitation” : “(Tiun, 2009)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Tiun, 2009). These high rise properties are being promoted because high rise living became a logical response to soaring of land prices. There are successful example countries that implement high rise such as Singapore and Hong Kong where the traditional lifestyle is high-density, high-rise living ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Tiun”, “given” : “Ling Ta”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “2nd Naprec Conference, Inspen”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2009” }, “page” : “1-25”, “title” : “Managing High-Rise Residential Building in Malaysia: Where Are We?”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=2880d3e8-caa0-428b-a2d7-1166ee2cf189” } , “mendeley” : { “formattedCitation” : “(Tiun, 2009)”, “plainTextFormattedCitation” : “(Tiun, 2009)”, “previouslyFormattedCitation” : “(Tiun, 2009)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Tiun, 2009).

In Penang, there is a trend of developers preferring to build tall building such as condominiums. In coming years, especially on Penang Island, there is a higher proportion of new high-rise units ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Lim”, “given” : “Kim Hwa”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “1”, “issued” : { “date-parts” : “2015” }, “title” : “Penang Economic Indicators Penang Economic Outlook 2015”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=d1e7c5cb-bf3a-4e15-8003-69fa855ad2cf” } , “mendeley” : { “formattedCitation” : “(Lim, 2015)”, “plainTextFormattedCitation” : “(Lim, 2015)”, “previouslyFormattedCitation” : “(Lim, 2015)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Lim, 2015). According to Table 2.1, on the statistics obtained from the National Property Information Centre ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “NAPIC”, “given” : “”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “7”, “issued” : { “date-parts” : “2012” }, “page” : “1-141”, “title” : “Laporan Stok Harta Tanah Property Stock Report Jadual Stok Harta Kediaman Q4 2012”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=bf0b0756-23a6-4d9d-a949-106d4139e47d” } , “mendeley” : { “formattedCitation” : “(NAPIC, 2012)”, “manualFormatting” : “(NAPIC)”, “plainTextFormattedCitation” : “(NAPIC, 2012)”, “previouslyFormattedCitation” : “(NAPIC, 2012)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(NAPIC), it is estimated that there were at least 203,618 units of high rise properties inclusive of flats, condominiums and apartments are under constructing for incoming supply in Malaysia by the end of 2017 and the number is growing yearly. From the data, Penang is the third highest state in constructing more high rise building which is about 35,793 units. This is due to the high demand of housing in this developing area.

2.3Size of Column and Beam
Based on a study on wind behavior of buildings with and without shear wall (in different location) for structural stability and economy ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Gourav P. Bajaj”, “given” : “Asst. Prof. G. B.

Bajaj, 2016), the column size is 600 mm x 600 mm and beam size is 500 mm x 300 mm. The building dimension is 20 m in length and 15 m in width with a height of 47.6 m. The research is about determination of shear wall application toward wind load which is similar to this study, the dimension of building is also almost similar in this study. Therefore, the size of column and beam is determined as 600 mm x 600 mm and 500 mm x 300 mm respectively.

2.4Shear Wall
Shear wall is a structural element installed in a building to resist horizontal forces parallel to the plane of the wall. Due to its highly in plane stiffness and strength, it can resist large both horizontal loads and support gravity loads simultaneously ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Sardar”, “given” : “Shahzad Jamil”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Karadi”, “given” : “Umesh.

The main horizontal forces that are induces by the shear wall are wind, earthquake and other lateral forces. They are mainly flexural members and mostly provided in high rise buildings to avoid the total collapse of the high rise buildings under seismic forces, wind forces or other lateral forces ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Gourav P.

When the buildings are tall, which are more than twelve storeys or so, the sizes of beam and column need to be constructed larger and reinforcement at the beam and column junction works become heavier, therefore, there is a lot of obstruction at to place and vibrate concrete at these joints, which generally will affect the safety of buildings ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Gourav P.

So, the present of shear walls in high rise buildings solves these practical difficulties. However, recent RC tall buildings would have more complicated structural behavior than before. Shear wall system with irregular openings are that undergoes both lateral and gravity loads, and may result some especial issues in the behavior of structural elements and stability of structure ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “Executions of the shear walls along the exterior perimeter of slender high rise buildings enhance the efficiency of such buildings to resist the seismic forces.

So, this study presents a considerable interest in establishing design guide lines for numerical investigation of seismic response of shear walls taking into account such openings and their locations. Five three dimensional models of different configurations of the openings are chosen and compared to figure out the best installation of openings having more efficiency on the performance of shear walls under earthquake excitation. Computer generated models are analyzed by SAP2000 program11 and the loading is considered using acceleration time history with a peak ground acceleration 0.25g provided in the new Egyptian code (ECOL2008)13 for seismic loads on structures and building works. The comparative results showed that the top displacement, base shears and stress distributions around the openings depend on the openings arrangement system. The results of staggered opening system in the shear walls (spatial arrangement) are very much close to those resulted in the shear walls without openings than the other opening arrangement cases.

But uncertainties in the locations of shear walls are very high because of the demandable architectural openings (windows u2013 doors) in the exterior views of such buildings. So, this study presents a considerable interest in establishing design guide lines for numerical investigation of seismic response of shear walls taking into account such openings and their locations. Five three dimensional models of different configurations of the openings are chosen and compared to figure out the best installation of openings having more efficiency on the performance of shear walls under earthquake excitation. Computer generated models are analyzed by SAP2000 program11 and the loading is considered using acceleration time history with a peak ground acceleration 0.25g provided in the new Egyptian code (ECOL2008)13 for seismic loads on structures and building works. The comparative results showed that the top displacement, base shears and stress distributions around the openings depend on the openings arrangement system. The results of staggered opening system in the shear walls (spatial arrangement) are very much close to those resulted in the shear walls without openings than the other opening arrangement cases. Finally the staggered arrangement of openings between the stories in shear walls are suggested to be applied in engineering practice since it satisfies both the architectural and seismic requirements.”, “author” : { “dropping-particle” : “”, “family” : “Abd-El-Rahim”, “given” : “Hamdy H A”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Farghaly”, “given” : “Ahmed Abdelraheem”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “Journal of Engineering Sciences, Assiut University”, “id” : “ITEM-1”, “issue” : “2”, “issued” : { “date-parts” : “2010” }, “page” : “421-435”, “title” : “Influence of Requisite Architectural Openings on Shear Walls Efficiency”, “type” : “article-journal”, “volume” : “38” }, “uris” : “http://www.mendeley.com/documents/?uuid=c40a0d51-3816-42a7-b379-a063f4fdd85c” } , “mendeley” : { “formattedCitation” : “(Abd-El-Rahim & Farghaly, 2010)”, “plainTextFormattedCitation” : “(Abd-El-Rahim & Farghaly, 2010)”, “previouslyFormattedCitation” : “(Abd-El-Rahim & Farghaly, 2010)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Abd-El-Rahim & Farghaly, 2010).

The space frame can be formed either in a flat or a curved surface. The earliest form of space frame structures is a single layer grid. By adding intermediate grids and including rigid connecting to the joist and girder framing system, the single layer grid is formed. The major characteristic of grid construction is the omni-directional spreading of the load as opposed to the linear transfer of the load in an ordinary framing system. Since such load transfer is mainly by bending, for larger spans, the bending stiffness is increased most efficiently by going to a double layer system. The load transfer mechanism of curved surface space frames essentially different from the grid system that is primarily membrane-like action ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Wai-fah”, “given” : “Ed Chen”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “1999” }, “title” : “Lan, T.T. u201c Space Frame Structures u201d”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=7b6d28c5-b232-4d85-ab2a-e5464423840b” } , “mendeley” : { “formattedCitation” : “(Wai-fah, 1999)”, “plainTextFormattedCitation” : “(Wai-fah, 1999)”, “previouslyFormattedCitation” : “(Wai-fah, 1999)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Wai-fah, 1999).
A good example of space structure is Baltimore-Washington International Thurgood Marshall Airport (BWI Airport) shown in Figure 2.1. Baltimore-Washington International Airport is an international airport located in Linthicum, an unincorporated community in northern Anne Arundel County, Maryland, United States. The airport has the signature space frame design while increasing passenger capacity and improving the traveler’s experience. The design is a 90-foot atrium, topped by a large skylight, floods the upper and lower levels, including waiting and shopping areas, with natural light, while supported by the steel space frame elements.

The advantage of a space frame structure is lightweight properties. The material is distributed spatially in such away that the loads transfer mechanism are primarily axial loads which are in tension or compression ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “http://doi.org/10.5169/seals-9530%0ANutzungsbedingungen”, “author” : { “dropping-particle” : “”, “family” : “Makowski”, “given” : “Z.S.”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “ETH-Bibliothek ETH Zurich, Ru00e4mistrasse 101, 8092 Zurich, Switzerland,”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2018” }, “page” : “127-148”, “title” : “Space structures”, “type” : “article-magazine” }, “uris” : “http://www.mendeley.com/documents/?uuid=59822e47-5457-4b65-910e-841462c379f4” } , “mendeley” : { “formattedCitation” : “(Makowski, 2018)”, “plainTextFormattedCitation” : “(Makowski, 2018)”, “previouslyFormattedCitation” : “(Makowski, 2018)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Makowski, 2018). Furthermore, space frames can be built from simple prefabricated units, which are often of standard size and shape. Such units can be easily transported and rapidly assembled on site by semi-skilled labor. Besides, space structure compatible with architecture aspect. Architects appreciate the visual beauty and the impressive simplicity of lines in space frames. A trend is very noticeable in which the structural members are left exposed as a part of the architectural expression. Desire for openness for both visual impact as well as the ability to accommodate variable space requirements always calls for space frames as the most favorable solution ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Wai-fah”, “given” : “Ed Chen”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “1999” }, “title” : “Lan, T.T. u201c Space Frame Structures u201d”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=7b6d28c5-b232-4d85-ab2a-e5464423840b” } , “mendeley” : { “formattedCitation” : “(Wai-fah, 1999)”, “plainTextFormattedCitation” : “(Wai-fah, 1999)”, “previouslyFormattedCitation” : “(Wai-fah, 1999)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Wai-fah, 1999).
2.6Space Shear Wall
Space Shear Wall is space trusses to resist the lateral forces generated by the wind activities. Such lateral forces may be resisted quite effectively by integration of three-dimensional structures with two dimensional lateral systems like cross bracing, where the building frame is designed to carry the vertical loads, and the bracing the lateral force ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.6088/ijcser.201304010021”, “author” : { “dropping-particle” : “”, “family” : “Bayat”, “given” : “Behzad”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Ghazali”, “given” : “Mohd Zulkifli M”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Tahir”, “given” : “Mahmood”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “2”, “issued” : { “date-parts” : “2014” }, “page” : “203-214”, “title” : “Space shear wall as an innovative seismic resistant system for structures”, “type” : “article-journal”, “volume” : “3” }, “uris” : “http://www.mendeley.com/documents/?uuid=57bae9a2-7783-4210-8e68-836501b0a3b8” } , “mendeley” : { “formattedCitation” : “(Bayat et al., 2014)”, “plainTextFormattedCitation” : “(Bayat et al., 2014)”, “previouslyFormattedCitation” : “(Bayat et al., 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Bayat et al., 2014).

Therefore, there is development of space structures in previous years. Space frame structure is a precious system that can optimise between engineer and architect to create a new forms, that provide wider application, flexibility and diversity.

2.7Lateral Load
Lateral loads are defined as the live loads in the form of horizontal force acting on the structure. Typical lateral loads would be a wind load against a facade, an earthquake, the earth pressure against a beach front, retaining wall or the earth pressure against the basement wall ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Hoogendoorn”, “given” : “P.P.”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “2009” }, “publisher” : “Delft University of Technology”, “title” : “Lateral load design of tall buildings”, “type” : “thesis” }, “uris” : “http://www.mendeley.com/documents/?uuid=9027ee76-4569-41da-90a7-90af71647c36” } , “mendeley” : { “formattedCitation” : “(Hoogendoorn, 2009)”, “plainTextFormattedCitation” : “(Hoogendoorn, 2009)”, “previouslyFormattedCitation” : “(Hoogendoorn, 2009)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Hoogendoorn, 2009). Most lateral loads vary in intensity depending on the buildings geographic location, structural materials, height and shape. The dynamic effects of wind and earthquake loads are usually analyzed as an equivalent static load in most small and moderate sized buildings ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Brownjohn”, “given” : “J.

2.7.1 Wind Behaviour
Wind is a phenomenon of great complexity because of the many flow situations arising from the interaction of wind with structures. Wind has some negative and positive effects. For structural engineers, it always causes trouble with height ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.1016/j.rser.2014.05.024”, “ISBN” : “1364-0321”, “ISSN” : “13640321”, “abstract” : “Today, energy has a key role in socio-economical development of a country. By exhausting fossil fuels as one of the largest energy consumption sources throughout the world, it seems to be vital to find renewable alternative energy sources or ways of reducing energy demands, especially in tall buildings with their great potential to use sustainable sources because of their height. In this study, the main problem is that the construction builders and users do not know the excessive energy saving potential of high-rise buildings. So, as a priority, this matter should be more concentrated on while designing by architects. These days, in my own country Iran, due to population growth and industrial development, the amount of energy consumption is increasing. This can show the importance of the problem. So, the Tehran International Tower, which is the highest residential tower in Iran, was chosen as a case study. Thus, the overall objective of this study is making tall building architects more aware of the neglected sustainable potential ways to diminish energy consumption. Meanwhile, this study tries to illustrate the effects of some environmental factors, such as air pressure and density, wind speed and other similar factors in high-rise buildings, from architects and ordinary peoples points of view and comparing these attitudes with each other in the case study. Finally, as buildings use a huge amount of generated energy in the world, and high-rise buildings are an inevitable part of the community, they can meaningfully contribute in reducing energy consumption by using renewable energies and new ideas in designing. Moreover, the result of this research shows that sustainable skyscrapers can be energy efficient and are closely related to their site and environment. u00a9 2014 Elsevier Ltd.”, “author” : { “dropping-particle” : “”, “family” : “Lotfabadi”, “given” : “Pooya”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “Renewable and Sustainable Energy Reviews”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2014” }, “page” : “285-295”, “publisher” : “Elsevier”, “title” : “High-rise buildings and environmental factors”, “type” : “article-journal”, “volume” : “38” }, “uris” : “http://www.mendeley.com/documents/?uuid=388249f5-1119-42ff-9a7e-98e0f195a1c5” } , “mendeley” : { “formattedCitation” : “(Lotfabadi, 2014)”, “plainTextFormattedCitation” : “(Lotfabadi, 2014)”, “previouslyFormattedCitation” : “(Lotfabadi, 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Lotfabadi, 2014).

More impor- tantly such a simplified treatment for deriving lateral loads does not address key design issues including dy- namic response (effects of resonance, acceleration, damping, structural stiffness), interference from other structures, wind directionality, and cross wind response, which are all important factors in wind design of tall buildings.

Therefore, high rise building which is tall or slender, respond dynamically to the effects of wind. In Penang, an estimation of maximum wind speed at a building with height of 145.6m was conducted and indicated the value of 29.85 m/s ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “The recent freak storm incident in Penang, Malaysia has caused damages to the facilities, uprooted trees and causing death. The aim of this study is to estimate the maximum wind speed at the highest level of a high-rise building that has caused the lightning arrestor to drop off and crashed. The wind speed data were collected from four meteorology stations located in Bayan Lepas, Butterworth, Alor Setar and Langkawi. GIS software was used to analyze, estimate and map the wind speed by applying surface interpolation. The interpolation process was conducted by applying the Inverse Distance Weighted (IDW) and Triangulated Irregular Network (TIN) method which are the functions in GIS software namely, IDRISI SELVA. From the plotted wind speed it shows that the result from IDW and TIN are 16.46 m/s and 16.43 m/s respectively.

By using the power law equation, the estimation of maximum wind speed at Tower A (145.6 m) was conducted and indicates the value of 29.85 m/s and 29.79 m/s.

Practically all building codes consider the wind action as a quasi-static load. To allow a static structural calculation, factors are introduced accounting for the spatial and temporal averaging of wind gustiness and the dynamic amplification of the building response ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.1016/j.engstruct.2017.05.071”, “ISSN” : “18737323”, “abstract” : “Equivalent Static Wind Loads (ESWLs) represent an extremely useful tool for the characterization of the structural response to the wind action and provide a convenient way for structural engineers in order to include the results of a complete, rigorous, buffeting analysis in the design process. Recently, a novel approach to the determination of ESWLs has been proposed which is based on the adoption of Proper Skin Modes for the characterization of the static/quasi-static structural response. In that study, the reconstruction of the extreme internal forces over the structure for all structural members has been performed in a least square sense and a smoothed version of the maximum/minimum operators, typical of envelope calculations, has been adopted.

2.7.3 Surface Wind Characteristics
Wind is defined as the motion of air with respect to the earth’s surface. The motion is caused by pressure differences in air layers of the same altitude ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.1016/j.engstruct.2017.05.071”, “ISSN” : “18737323”, “abstract” : “Equivalent Static Wind Loads (ESWLs) represent an extremely useful tool for the characterization of the structural response to the wind action and provide a convenient way for structural engineers in order to include the results of a complete, rigorous, buffeting analysis in the design process.

These different air pressures are caused by variable solar heating of the atmosphere. Since buildings are located at the surface of the earth we are especially interested in the surface wind characteristics. The surface wind characteristics include variation with height and terrain roughness, turbulence and pressure ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Hoogendoorn”, “given” : “P.P.”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “2009” }, “publisher” : “Delft University of Technology”, “title” : “Lateral load design of tall buildings”, “type” : “thesis” }, “uris” : “http://www.mendeley.com/documents/?uuid=9027ee76-4569-41da-90a7-90af71647c36” } , “mendeley” : { “formattedCitation” : “(Hoogendoorn, 2009)”, “plainTextFormattedCitation” : “(Hoogendoorn, 2009)”, “previouslyFormattedCitation” : “(Hoogendoorn, 2009)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Hoogendoorn, 2009).

Variation with height and terrain roughness means that the surface wind varies strongly with height. It is approximately zero at the surface, and it increases with height in a boundary layer depth; ranging approximately from 100 m for low wind velocities over smooth surfaces to 4 km for extreme winds over rough surfaces. This layer is called the atmospheric boundary layer, and is schematically sketched in Figure 2.7. Above this boundary layer the wind flows approximately with a constant gradient wind velocity along the pressure isobars.

Figure 2.7: Boundary Layer of Wind
The wind flow is highly turbulent in three dimensions when near to the earth’s surface. Turbulent velocity fluctuations in the air flow passing a point can be considered to be caused by a superposition of rotating “eddies”, transported by the wind with the mean velocity. These rotating eddies are three-dimensional turbulent vortices of varying size ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “In recent years, especially in the crowded city-centers where land prizes have become extremely high, tall buildings with more than 30 floors have started to be designed and constructed in Turkey. On the other hand, the technical improvements have provided the opportunity of design and construction of more slender structures which are influenced by the wind actions more. If the building is flexible, wind can interact with it so the wind induced oscillations can be significantly magnified. In order to analyze the response of such buildings under wind effects, wind tunnel tests are accepted to be the most powerful tool all over the world. In this study, a series of tests were performed in Ankara Wind Tunnel on a model building in the shape of a rectangular prism. For the similitude of flow conditions, passive devices were designed. The response of the model building was measured through a high frequency base balance which was designed specifically for this case study.

Pressure is the force exerted on the surface per unit area. Depending on the wind direction and the porosity distribution of the building envelope, they can act in the same or opposite direction. The reference pressure in wind engineering is taken as the ambient pressure being the atmospheric pressure for true scale buildings. A pressure above atmospheric is called positive and below atmospheric is denominated negative or suction. There is a stagnation point on the windward side of buildings where the wind is completely blocked ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Eurocode 1”, “given” : “”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “2006”, “issued” : { “date-parts” : “2010” }, “title” : “Eurocode 1: Actions on structures – Part 1-4: General actions – Wind actions”, “type” : “article-journal”, “volume” : “7” }, “uris” : “http://www.mendeley.com/documents/?uuid=b7720c22-0d97-4b9b-93f9-3c2a8ae80420” } , “mendeley” : { “formattedCitation” : “(Eurocode 1, 2010)”, “plainTextFormattedCitation” : “(Eurocode 1, 2010)”, “previouslyFormattedCitation” : “(Eurocode 1, 2010)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Eurocode 1, 2010).

2.7.4 Structural Factor
The quasi-static approach of wind loading in the Eurocode requires the use of an additional factor to account for the dynamic effects in a static calculation. The Eurocode denominates the total dynamic effect as the structural factor. The structural factor is defined as the product of the size factor and the dynamic factor. The size factor cs takes the improbability into account of the simultaneous presence of wind gusts over the building surface. The dynamic factor cd takes into account the amplification of the structural response due to the resonance of the building structure with the longitudinal turbulence ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Eurocode 1”, “given” : “”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “2006”, “issued” : { “date-parts” : “2010” }, “title” : “Eurocode 1: Actions on structures – Part 1-4: General actions – Wind actions”, “type” : “article-journal”, “volume” : “7” }, “uris” : “http://www.mendeley.com/documents/?uuid=b7720c22-0d97-4b9b-93f9-3c2a8ae80420” } , “mendeley” : { “formattedCitation” : “(Eurocode 1, 2010)”, “plainTextFormattedCitation” : “(Eurocode 1, 2010)”, “previouslyFormattedCitation” : “(Eurocode 1, 2010)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Eurocode 1, 2010).

Several approaches to the determination of ESWLs have been presented. The gust loading factor approach, in its simplest version, assumes that the structural response to the time averaged wind profile can be appropriately amplified in order to synthetically take into account the structure dynamic response. Such an approach, although still widely used in practice due to its simplicity, is prone to numerous limitations, the principal one being the impossibility to describe effects which are null when the time averaged response is considered ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.1016/j.engstruct.2017.05.071”, “ISSN” : “18737323”, “abstract” : “Equivalent Static Wind Loads (ESWLs) represent an extremely useful tool for the characterization of the structural response to the wind action and provide a convenient way for structural engineers in order to include the results of a complete, rigorous, buffeting analysis in the design process.

The equivalent static wind load of this study is calculated by referring Uniform Building Code 1997. The uniform building code is dedicated to the development of better building construction and greater safety to the public by uniformity in building laws. The code is founded on broad-based performance principles that make possible the use of new materials and new construction systems.

Every building should be designed and constructed to resist the wind effects by determining the requirements in uniform building code 1997. Wind should be assumed acting from any horizontal direction. The wind pressure cannot be reducted due to any shielding effect of adjacent structures. The structures which are sensitive to dynamic effects, such as buildings with a height-to-width ratio greater than five, and buildings over 400 feet in height, should be designed in accordance with approved national standard ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “ISBN” : “ISSN: 0896-9655”, “PMID” : “20069301”, “author” : { “dropping-particle” : “”, “family” : “UBC”, “given” : “”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “1997” }, “page” : “20 p.”, “title” : “Uniform building code”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=98c600e1-1a0f-4715-a64b-5375d3da658a” } , “mendeley” : { “formattedCitation” : “(UBC, 1997)”, “plainTextFormattedCitation” : “(UBC, 1997)”, “previouslyFormattedCitation” : “(UBC, 1997)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(UBC, 1997). Therefore, UBC 1997 acts as a guideline, which can ensure the safety and stability of the every structures by following standard design procedure in UBC 1997.

The total pressure from wind load can be calculated by applying the formula listed in UBC 1994 section 2316. This formula is listed below :
P = Ce Cq qs I (2.2)
Where P = design wind pressure
Ce = combined height, exposure and gust factor coefficient as given in Table 2.7.5.1 in Appendix A
Cq= pressure coefficient for the structure or portion of structure under consideration as given in Table 2.7.5.2 in Appendix B.

qs = wind stagnation pressure at the standard height of 33 feet (10000 mm) as set forth in Table 2.7.5.3 in Appendix C.

l = importance factor as set forth in Table 2.7.5.4 in Appendix D.

2.8.1 Lateral Displacement
As far as the ultimate limit state is concerned, building displacements due to horizontal loads must be limited to prevent collapse due to P-delta effects. P-Delta effect is secondary order loading effect which will happen in structure directly related to stiffness of building, The P-delta effect reduces the stiffness of structural elements ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “DOI” : “10.9790/1684-1044249”, “ISBN” : “1684104424”, “author” : { “dropping-particle” : “”, “family” : “Yousuf Dinar”, “given” : “”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Samiul Karim”, “given” : “”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Ayan Barua”, “given” : “”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Ashraf Uddin”, “given” : “”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE)”, “id” : “ITEM-1”, “issue” : “4”, “issued” : { “date-parts” : “2013” }, “page” : “42-49”, “title” : “P- Delta Effect in Reinforced Concrete Structures of Rigid Joint”, “type” : “article-journal”, “volume” : “10” }, “uris” : “http://www.mendeley.com/documents/?uuid=7af480f3-a321-43c4-b7ef-d7cb47477963” } , “mendeley” : { “formattedCitation” : “(Yousuf Dinar, Samiul Karim, Ayan Barua, & Ashraf Uddin, 2013)”, “plainTextFormattedCitation” : “(Yousuf Dinar, Samiul Karim, Ayan Barua, & Ashraf Uddin, 2013)”, “previouslyFormattedCitation” : “(Yousuf Dinar, Samiul Karim, Ayan Barua, & Ashraf Uddin, 2013)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Yousuf Dinar, Samiul Karim, Ayan Barua, ; Ashraf Uddin, 2013). In the serviceability limit state, the lateral displacements are to be limited to prevent damage to or malfunctioning of non-structural components such as cladding on the building façade, partitions and interior finishes (doors, elevators, etc.). These problems in non-structural elements are caused by inter-storey drift. No universally adopted criterion exists with regard to the lateral displacement limit in the serviceability limit state ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Hoogendoorn”, “given” : “P.P.”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “2009” }, “publisher” : “Delft University of Technology”, “title” : “Lateral load design of tall buildings”, “type” : “thesis” }, “uris” : “http://www.mendeley.com/documents/?uuid=9027ee76-4569-41da-90a7-90af71647c36” } , “mendeley” : { “formattedCitation” : “(Hoogendoorn, 2009)”, “plainTextFormattedCitation” : “(Hoogendoorn, 2009)”, “previouslyFormattedCitation” : “(Hoogendoorn, 2009)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Hoogendoorn, 2009).
Nevertheless, values of the inter-storey drift of up to H/400 are normally considered as acceptable. In order to avoid an exhaustive calculation of all storey displacements, usually a global drift criterion is adopted with a limit of H/500, where H refers to the building height. Note that the overall drift criterion can be more or less conservative depending on the displacement diagram, i.e. whether the displacement diagram is shear or bending-dominated ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “Hoogendoorn”, “given” : “P.P.”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issued” : { “date-parts” : “2009” }, “publisher” : “Delft University of Technology”, “title” : “Lateral load design of tall buildings”, “type” : “thesis” }, “uris” : “http://www.mendeley.com/documents/?uuid=9027ee76-4569-41da-90a7-90af71647c36” } , “mendeley” : { “formattedCitation” : “(Hoogendoorn, 2009)”, “plainTextFormattedCitation” : “(Hoogendoorn, 2009)”, “previouslyFormattedCitation” : “(Hoogendoorn, 2009)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Hoogendoorn, 2009).

2.9Wind Tunnel Test
Wind Tunnel Test is a powerful tool that allows engineers to determine the nature and intensity of wind forces acting on complex structures. Wind tunnel testing is particularly useful when the complexity of the structure and the surrounding terrain, resulting in complex wind flows, does not allow the determination of wind forces using simplified code provisions ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “ISSN” : “14439255”, “abstract” : “Simple quasi-static treatment of wind loading, which is universally applied to design of typical low to medium-rise structures, can be unacceptably conservative for design of very tall buildings. On the other hand such simple treatment can easily lead to erroneous results and under-estimations. More impor- tantly such a simplified treatment for deriving lateral loads does not address key design issues including dy- namic response (effects of resonance, acceleration, damping, structural stiffness), interference from other structures, wind directionality, and cross wind response, which are all important factors in wind design of tall buildings.

The first attempts for building up such kind of a laboratory was resulted from the need of understanding the lift and drag forces acting on surfaces cutting through the atmosphere for the purpose of designing and making a flying machine ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “In recent years, especially in the crowded city-centers where land prizes have become extremely high, tall buildings with more than 30 floors have started to be designed and constructed in Turkey.

Wind tunnel experiments for tall buildings can be divided into three type which are synchronous multi-pressure scanning system (SM-PSS), high frequency base balance (H-FBB) and aeroelastic model tests. The SM-PSS tests types of the wind tunnel tests that are based on the pressure fluctuations on the models. The main purpose in this type is to measure the time series of instantaneous pressure distributions occurring on the exterior surfaces of the model utilizing pressure tubes mounted on it. Since the pressure fluctuation monitoring is the basis of the SM-PSS tests, they are mostly preferred for the pressure based design works such as the cladding design and the design of large-area roof systems. SM-PSS tests are very useful in the development and improvement works of the building design specifications since the codes approach to wind loading problems from the pressure point of view ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “In recent years, especially in the crowded city-centers where land prizes have become extremely high, tall buildings with more than 30 floors have started to be designed and constructed in Turkey.

The second type is the high frequency base balance (H-FBB) which is a type of a data acquisition and processing system that consists of ultra-sensitive force measurement arrangements. The balance system constitutes of ultra sensitive load cells for the purpose of measuring the five base response components that are basically the moments about the three orthogonal axes (x,y,z) and the two base shears as time series. Besides, the third type is aeroelastic test. When a lightly damped, low mass and highly flexible structure experiences wind-induced oscillations, the deformations in turn lead to amplifications in the wind loads that the structure feels. This phenomenon is known as wind / structure interaction and it may result in aeroelastic instability with a possible unfavourable consequence such as inadmissible deformations/accelerations or it may also result in lesser extreme effects than predicted ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “In recent years, especially in the crowded city-centers where land prizes have become extremely high, tall buildings with more than 30 floors have started to be designed and constructed in Turkey.

CHAPTER 3METHODOLOGY
3.1IntroductionThis chapter discussed about the design of the structural, dimension of the structure, parameter of study, assignment of wind speed, and the method of the testing on the structural in order to obtain the lateral performance under wind loading. Initially, the problem statement is determined in order to develop the ideas of the title. After that, three objectives are decided based on the problem statement to scope down the research field. Literature Review is then been carry out to study more on the paper that have been done from the previous researcher which are related. The papers that have been reviewed are regarding the high rise building, wind load, space shear wall, lateral performance of building against wind, analysis and the method that used to obtain the result in the testing on the structural. In these chapter, the way to obtain the parameter will be discussed. The steps of design, assign and analyse in SAP2000 are shown. 16 storey building with and without space shear wall is design and analysed by using SAP2000. In addition, down scale models will be constructed and tested in wind tunnel. The flow chart is showed on the Figure 3.1.
3.2Flow Chart of Overall Research
The flow chart for overall research activities is shown in the Figure 3.1.

Figure 3.1: Flow Chart of Methodology
3.3Parameter
The parameters required in this study are height of building, base dimension of building, wind speed at Penang. All the informations are referred journal or thesis from previous related research and standard. According to the manual of standard building specification ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “author” : { “dropping-particle” : “”, “family” : “European Commission”, “given” : “”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “id” : “ITEM-1”, “issue” : “December”, “issued” : { “date-parts” : “2011” }, “page” : “373”, “title” : “Manual of standard building specifications”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=a08c0d61-f1aa-4fac-a160-3d89dcb40320” } , “mendeley” : { “formattedCitation” : “(European Commission, 2011)”, “plainTextFormattedCitation” : “(European Commission, 2011)”, “previouslyFormattedCitation” : “(European Commission, 2011)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(European Commission, 2011), the typical height for a normal building for general purpose is 3.0m. Therefore, the floor to floor height of this study is decided to be 3.0m as well. As stated in 2.2 (High Rise Building), the high rise building is defined as a building which having between sixteen to fifty stories. To meet the high rise building requirement, the building in this study is 16 stories, which by multiply by 3.0m for each floor, the total building height is 48m.
As discussed in 2.2 (High Rise Building), the slenderness of this building (height-to-base ratios) is decided as 4:1. This indicated that the narrowest width of building is 12m. Therefore, the base dimension of building are 20 m in length and 12 m in width. The layout plan of this building is shown in Figure 3.2. Whereas, Figure 3.3 shows the direction of wind exert on the building.

3.4Determination of Wind Speed
To determine the wind load to be assigned in structure design analysis, the data of maximum wind speed, average wind speed, maximum wind gust and average wind gust are obtained from Weather Underground. The data obtained is from the year 2013 to 2017 and set location in Penang.

From Figure 3.4, the data showed the highest maximum wind speed from 2013 to 2017 is 42 km/h (11.67 m/s) and the highest average wind speed from 2013 to 2017 is 11 km/h (3.06 m/s). While, the lowest maximum wind speed and average wind speed from 2013 to 2017 are 5 km/h (1.39 m/s) and 23 km/h (6.39 m/s) respectively. Besides that, the highest maximum wind gust from 2013 to 2017 is 69 km/h (19.17 m/s) and the highest average wind gust from 2013 to 2017 is 52 km/h (14.4 m/s). Whereas, the lowest maximum wind speed and average wind speed from 2013 to 2017 are 27 km/h (7.5m/s) and 32 km/h (8.89 m/s) respectively. This shows that there are no much different between the highest and lowest wind speed, the wind in Penang can be consider as static wind.
Furthermore, based on 2.6.1, an estimation of maximum wind speed at a building with height of 145.6 m was conducted and indicated the value 29.85 m/s in Penang ADDIN CSL_CITATION { “citationItems” : { “id” : “ITEM-1”, “itemData” : { “abstract” : “The recent freak storm incident in Penang, Malaysia has caused damages to the facilities, uprooted trees and causing death. The aim of this study is to estimate the maximum wind speed at the highest level of a high-rise building that has caused the lightning arrestor to drop off and crashed. The wind speed data were collected from four meteorology stations located in Bayan Lepas, Butterworth, Alor Setar and Langkawi. GIS software was used to analyze, estimate and map the wind speed by applying surface interpolation. The interpolation process was conducted by applying the Inverse Distance Weighted (IDW) and Triangulated Irregular Network (TIN) method which are the functions in GIS software namely, IDRISI SELVA. From the plotted wind speed it shows that the result from IDW and TIN are 16.46 m/s and 16.43 m/s respectively. Surface interpolation method was used to estimate the maximum wind speed at 10 m height. By using the power law equation, the estimation of maximum wind speed at Tower A (145.6 m) was conducted and indicates the value of 29.85 m/s and 29.79 m/s. Thus, estimation of maximum wind speed can be approached to determine the value at certain location using these two methods; IDW and TIN and conventional power law method was used to find the value of wind speed at certain height.”, “author” : { “dropping-particle” : “”, “family” : “Deraman”, “given” : “Che”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” }, { “dropping-particle” : “”, “family” : “Chik”, “given” : “Wan”, “non-dropping-particle” : “”, “parse-names” : false, “suffix” : “” } , “container-title” : “Advances in Civil, Environmental, and Materials Research (ACEM14)”, “id” : “ITEM-1”, “issued” : { “date-parts” : “2014” }, “title” : “Case Study: Wind Speed Estimation of Wind Storm Damage in Penang Using Surface Interpolation Method and Wind Speed Profiling”, “type” : “article-journal” }, “uris” : “http://www.mendeley.com/documents/?uuid=daeedca1-c424-4bca-9059-8558681215ae” } , “mendeley” : { “formattedCitation” : “(Deraman & Chik, 2014)”, “plainTextFormattedCitation” : “(Deraman & Chik, 2014)”, “previouslyFormattedCitation” : “(Deraman & Chik, 2014)” }, “properties” : { }, “schema” : “https://github.com/citation-style-language/schema/raw/master/csl-citation.json” }(Deraman ; Chik, 2014).

3.5Equivalent Static Wind Load
Base on Uniform Building Code 1997, equivalent static wind load can be computed by using equation 2.2 which the details of the equation was discussed in Chapter 2. Ce is the coefficient of combined height, exposed and gust factor which can be obtained by referring Table 2.7.5.1 in Appendix A. Penang is a town which might surrounded by others building, so it is considered as exposure B. By interpolating of level height, the Ce value can be obtained for each level. The structure is primary frames and system, so the values of Cq are 0.8 for windward wall and 0.5 for leeward wall by referring Table 2.7.5.2 in Appendix B. As mention in 3.4, the wind speed decided to be used is 32.5 m/s (72.7 mph), the qs value can be obtained by referring Table 2.7.5.3 in Appendix C, which the qs is 16.4 psf. By referring Table 2.7.5.3 in Appendix D, the important factor lw is 1 since the structure is standard occupancy structure. Table 3.1 below summarise the parameter to be used.

3.6Configuration of Space Shear Wall
2 types of configuration of space shear wall will be installed in the structure. The space shear wall will be installed at the wall side which parallel to the axis that will be exert the wind loading for all 16 stories. For model 1, which will be the structure installed with typical shear wall as the control specimen. For model 2, the space shear wall will be installed fully at the for 4 bay of structure while model 3 will only be installed at the center 2 bay of structure only. Figure 3.6 and Figure 3.7 shows the model of configuration of space shear wall.

3.7Analysis of Structure
By collecting all data and parameter needed, the analysis of structure can be done by using SAP 2000. As mention in 2.3 (Size of Column and Beam), the size of column is 600 mm x 600 mm while the size of beam is 500 mm x 300 mm. The material will be Concrete Grade M25 with main and secondary steel reinforcement of Grade 500. The equivalent static wind load is obtained as calculated in 3.5 and to be assigned in SAP 2000 analysis. The principal steps to analyse using SAP 2000 are define material, define beam and column sections, design geometry of model, assign support, define load patterns, assign loading, define load combination. After that, the analysis can be run and results obtained can be interpreted by graphically review or table of data.

Firstly, as launch the software SAP 2000, a new file is opened by selecting new model in File tab. 3D frame is selected and the unit is set as kN, mm, C as shown in Figure 3.8 below. By inserting 16 stories, 3000 mm storey height, 4000 mm bay width for X direction, 3000 mm for Y direction, 5 bays in X direction and 4 bays in Y direction as shown on Figure 3.9.

Figure 3.8: Selection 3D frame and unit of kN, mm, C.

Figure 3.9: Dimension of 3D frame
After that, adding new material property of Concrete M25, with strength of 25 N/mm2 and its properties. Adding another new material for reinforment steel bar, with strength 500 N/mm2 and its properties. Materials defined shows in Figure 3.10. By then, frame sections are defined which are Column 600 mm x 600 mm and Beam 500 mm x 300 mm shown in Figure 3.11. The material for both is conrete M25 with rebar Grade 500.

In this research, since the objective is to study the lateral performance of structure when acting on wind, only static wind load will be defined and assigned to the structure. The wind load is based on the calculation in 3.5, which is computed based on the wind speed in Penang and condition. The auto lateral load pattern is selected for UBC 97 and the wind speed and exposure are modified as shown in Figure 3.12 and Figure 3.13.

3.8Wind Tunnel Testing
After simulation analysis by using SAP 2000, a down scale model will be constructed and carried out wind tunnel test in UTM wind tunnel. UTM wind tunnel is a closed circuit type which the air is continuously recirculated leading to a less noisy and an efficient test. The test section is 2.0 m width x 1.5 m height x 5.8 m Length, built by solid wall. The maximum wind speed can be achieved 80 m/s. For this study, the wind speed will be set as 32.5 m/s. The testing result will be discussed and compare with result from simulation analysis in Chapter 4.
