Abstract: Buildings in Singapore were designed primarily for gravity loads, but they are subjected to tremors due to far field effects of earthquakes in Sumatra. Thus, this study focuses on the evaluation of seismic vulnerability of frame and shear wall structures in Singapore, by comparing the demand curve and capacity curve in the acceleration-displacement format. The demand curve is obtained based on the accelerograms of bedrock motions due to the worst earthquake scenario in Sumatra, and soil profiles of the selected sites. To establish a reliable and elegant finite element analytical model to determine the capacity of a full scale building, experimental studies of a 1/5-scale shear wall model and a 1/2-scale frame model, under pushover and cyclic loading, were carried out. A retrofitting scheme using fiber reinforced polymer (FRP) system for shear wall structures was also investigated. The modeling parameters were obtained from the tests, and the established FEA models were verified using the test results.
