Earthquake resistance school building using Peninsular Malaysia bedrock response spectrum

Abstract

Response spectrum is a very useful tool in earthquake engineering for estimating the performance of structures. In this research, attenuation equation will be used to find the response spectrum of bedrock to predict reliable and more accurate ground motions as far 700 km from potential earthquake sources. School building can be made to resist earthquake using the data of this response spectrum. According to historical records, the earthquakes that influenced Peninsular Malaysia are originated from two earthquake faults: the Sumatra subduction zone and Sumatra great fault zone. The worst earthquake ever occurred in Sumatra subduction zone is identified as Mw = 9.11 and Mw = 7.81 for Sumatra fault zone. These data were then used to predict the response spectrum of bedrock in Malaysia using Probabilistic Seismic Hazard Analysis (PSHA). The response spectrum data accumulated is then use to study on the performance of the school building during earthquake. Analysis of building shows that the values of moment for combination load 2 increases about 15.07 percents for column 1 and approximately 4.70 percents for beam 2. Based on the results, the resultant forces of school building during earthquake loadings are larger than without earthquake loading.
