Abstract—Bridge is an essential lifeline structure, which provides an emergency link in transportation network system. During post-earthquake bridge should remain functioning without any collapse. But in reality, uncertainty behavior of civil engineering structures involve during service life since, actual and assumed environmental conditions during design are never coincide. The purpose of this paper is to evaluate the probabilistic failure of bridge pier subjected to far field ground motion. A nonlinear static pushover and incremental dynamic time-history analysis have been performed using the SeismoStruct nonlinear analysis program for 3D bridge bent. 20 far field ground motions and their respective PGA are considered to develop fragility curve for conventional and FRP retrofitted bridge pier. The purpose of this study is to probabilistic determination of seismic vulnerability of bridge pier and help to decision making for effective retrofitting technique.
