A simplified approach to evaluate cyclic response and seismic fragility of corrosion damaged RC bridge piers

Safety of the existing corrosion damaged reinforced concrete (RC) bridges during a seismic event is matter increasing concern. To reduce enormous economic loss and casualties, it important to examine potential risk corroded RC bridge structures. This paper presents simplified method determine fragility piers by developing FEM model analysis. make proposed approach realistic, numerical validated with two different experimental studies available in literature. Obtain results from demonstrated excellent agreement tests, making suitable for vulnerability After validation, further adopted perform non-linear static pushover analysis piers. Finally, recently developed software tool SPO2FRAG utilized carry out defining three damage levels.
