Abstract

Earthquake impact was not considered previously in the design of structure but now a days, seismic analysis and design play a vital role while designing any struc- ture. Similarly, for bridge structures, in the context of forecasting the performance of bridges in seismic events in speci ed risk prone environment, the use of fragility curves facilitates a coherent probabilistic method to predict the damage or loss of a structural system. The fragility curves are plotted to o er a forecast of possible destruction caused to a structure during an earthquake. In this study, nite ele- ment models of bridge are developed by using MIDAS Civil software. The bridge vulnerability due to seismic conditions is predicted by considering the age param- eter of the bridge.
