Abstract
This study presents a seismic retrofit strategy of buildings related to the site geological characteristics, and a case study is demonstrated in this study. An old temple had been retrofitted several times but still suffered damages continually from recent earthquakes. In order to find out a good retrofit strategy to strengthen the temple, we studied the strong motion characteristics of earthquake records by using response spectrum analysis from a nearby seismic station. The results indicated that increasing the building's stiffness would also increase the input energy. Therefore, we proposed another retrofit scheme by consuming earthquake energy instead of increasing the building's stiffness. In order to quantify the effects of the retrofit schemes, a computer structural model of the target building was built and its accuracy was verified by using ambient vibration experiment. In this study, a conceptual strengthening model was developed and the 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
