【 摘 要 】

This study shows the effect of various numerical models on the development of analytical fragility curves for bridge piers. Two distinct models are compared: model with a single degree of freedom, and the proposed full bridge model. Bridge pier damage indexes are obtained by performing both dynamic and static nonlinear analyses (pushover and time history analysis), in order to develop fragility curves for this bridge pier. It was observed that capacity curves, ductility curves, and fragility curves, are sensitive to structural modelling.
