Abstract

This study demonstrates that geological characteristics will affect seismic retrofit strategy. An old temple had been retrofitted before but still suffered serious damage from recent earthquakes. In order to find a good solution to strengthen the temple, a computer structural model of the target building was built and its accuracy was verified by using ambient vibration experiment. From nearby seismic station records, we then studied the strong motion characteristics using response spectrum analysis. The results indicated that increasing the building's stiffness would also increase the input energy. Therefore, we proposed another retrofit scheme to consume earthquake energy instead of increasing the building's stiffness. A conceptual strengthening model was developed and computer analysis was targeted for the temple's inter-story drift ratio to be kept under 0.5%. The effect of the final design was analyzed and discussed.
