| dc.description.abstract | Despite experienced earthquakes from local origin, tremors from neighbouring active seismic countries are felt in Peninsular Malaysia. The buildings subjected to local and distant earthquakes are posed with different damage potentials due to local site condition. This dissertation presents the effect of soil amplification for sediments with different soil classes and the structural responses of buildings with different heights subjected to near-field and far-field ground motions. Class C and E soil profiles determined from field measurement were considered to estimate the ground surface motions based on seven near-field and seven far-field bedrock motions recorded at different seismic stations in Peninsular Malaysia during various earthquake events. Structural responses of reinforced concrete moment-resisting frame buildings with varying heights on Class C and E sites subjected to near-field and far-field ground motions were analyzed using ETABS software. The results show that near-field bedrock motions have short period contents while far-field bedrock motions have long period contents. The calculated soil amplification factors show that the maximum acceleration and amplification factor for Class C and E sites subjected to far-field ground motions are higher than that subjected to near-field ground motions. From the developed acceleration response spectra, maximum spectral acceleration developed from both near-field and farfield ground motions on Class C site is higher than that on Class E site. The results with structural response of base reaction, storey deflection and inter-storey drift of buildings show that three-storey building that subjected to near-field ground motions give larger responses, whereas eight and 15-storey buildings on Class C and E sites that subjected to far-field ground motion result in higher responses. Generally, Malaysia National Annex gives higher prediction on the response of most of the buildings on Class C and E sites that subjected to both near-field and far-field ground motions. | en_US |
