[P01-27] Fragility Analysis of Existing Bridge Systems Focusing on Traffic Passability after Earthquake Event
Keywords:Fragility analysis, Pile bent pier, Siemic isolated bridge, Vehicle passability
After a major earthquake event, there is a case that the vehicles cannot become passing on the bridge due to the damages in bearings and expansion joints caused by large dynamic displacement. In this study, the fragility analysis was conducted focusing on the vehicle passability after the earthquake event on two bridges with different structural characteristics considering the effects of deterioration damages on the existing bridges. As the results, it was shown that the deterioration damage affected the large vehicles passability after the earthquake, and may decrease the vehicle passability as the bridge structure system.
