Abstract
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%.
