DEVELOPMENT OF FRAGILITY CURVES FOR THE ISOLATED AND NON-ISOLATED HIGHWAY BRIDGES BASED ON NUMERICAL SIMULATION

| 抄録（英）： |
The trend of base-isolating highway bridges is on the rise after the recent large earthquakes in Japan, the United States, and other countries. Recent investigation shows that the base-isolated system performs well against seismic forces as the substructures of such system experience less lateral forces due to energy dissipation of the isolation device. In this study, two reinforced concrete (RC) bridges are considered, of which one is an isolated system and the other one is a non-isolated system, and the fragility curves for the both systems are developed with respect to ground motion parameters based on numerical simulation using two hundred and fifty (250) strong motion records. It was observed that the level of damage probability for the isolated system is less than that of the non-isolated one.
