A comparison of structural design of a three-storey reinforced concrete school building in malaysia based on ubc 97 and bs8110/Muhammad Faiz Abdul Rahman
Masyarakat Malaysia tidak mengambil berat tentang bahaya gempa bumi kerana tiada sebarang sejarah direkodkan membabitkan gempa bumi yang menyebabkan kehilangan nyawa dan kerosakan teruk terhadap harta benda. Tetapi, Tsunami yang berlaku di perairan India pada 26 Disember 2004 menimbulkan satu tanda tanya terhadap masyarakat Malaysia; tentang keselamatan bangunan yang terdapat di Malaysia terhadap gempa bumi. Kerajaan dan pihak berkuasa tempatan kini mula membincangkan isu yang berkaitan dengan rekabentuk bangunan dengan mengambil kira beban seismik. Objektif utama disertasi ini adalah untuk membandingkan perbezaan peratusan kuantiti besi dan isipadu konkrit untuk rasuk dan tiang pada bangunan sedia ada yang direka bentuk menggunakan kod “British Standard” (BS 8110) dan rekabentuk mengunakan kod “Uniform Building Code” (UBC 97). Satu bangunan sekolah sedia ada di Malaysia telah dipilih. Plan bangunan tersebut berbentuk L dan mepunyai 3 tingkat. Hanya satu daripada blok bangunan sekolah tersebut dipilih untuk kajian ini. Malaysia berada dalam zon seismik yang rendah ke sederhana yang dikategorikan dalam zon 2B, berdasarkan kod UBC97. Struktur sekolah tersebut dikategorikan sabagai bangunan biasa dan perlu di analisis menggunakan kaedah bersamaan statik. Analisis seismik dilakukan menggunakan perisian komputer STAAD-Pro. Bangunan tersebut direka bentuk menggunakan “moment resisting frame” berdasarkan kod UBC 97 dan kod ACI 95. Jumlah perbezaan kuantiti besi antara bangunan sedia ada dan bangunan yang direka bentuk menggunakan kod seismik ialah 26.16% manakala untuk isipadu konkrit perbezaannya ialah 13.05%.

Malaysians were not too concern about earthquake hazards because earthquake had not caused any serious property damage or casualty in Malaysia in the recent recorded history. But, the Indian Ocean Tsunami on 26 December 2004 raised one important question for Malaysia: How safe are buildings against the earth movements? The safety of buildings in Malaysia subjected to seismic loading had become an issue. The government and local authorities now start to discuss about the important of building with consideration of seismic load in Malaysia. The main objective of this dissertation is to compare in term of percentage of steel tonnage and concrete volume for beam and column of existing gravity load design RC school buildings (BS 8110) in Malaysia and the seismic design based on Uniform Building Code (UBC 97). One existing school model was selected, L shape in plan consisting of 3 stories and only one block is considered for the study. Malaysia is in low to moderate seismicity region, which is in zone 2B, based on UBC 97 code. The school is categorized as regular structures and hence is analyzed using static equivalent method. The seismic analysis is performed using STAAD-Pro software. The structures are designed as Intermediate Moment Resisting Frame (IMRF) according to the UBC 97 and ACI 95 recommendations. Analysis of result the result show that he total percentage difference between existing design and seismic design for steel tonnage is 26.16% and for concrete volume is 13.05%.
