Structural Response of Building in Ranau, Kota Kinabalu and Lahad Datu, Sabah Under Different Earthquake Scenarios
In June 2015 Malaysia experienced the strongest earthquake in recent years as a magnitude 6.0 earthquake struck Ranau and damaged many buildings in the region of Ranau and Kundasang. Since this earthquake event, seismic design for East Malaysia has become a concern for many engineers and researchers to prevent seismic damage of important structures and infrastructures in the future. This paper covers the structural analysis of a typical four storey reinforced concrete building in three main cities of Sabah namely Ranau, Kota Kinabalu and Lahad Datu. Four earthquake scenarios were considered in the structural analysis including two largest historical earthquakes and two forecast earthquakes. It is found that out of the three cities included in this study, building in Lahad Datu has the most drastic structural response followed by Ranau and Kota Kinabalu. Based on the result of this study, buildings in Ranau and Lahad Datu is expected to experience damage in forecast earthquake. Assessment and retrofitting of important building is required to increase seismic capacity of buildings.
