This work is started from study of failures of bridges due to various earthquakes and also the types of failure with the help of various literature. The focus of study is on Elevated metro bridges. Design and analysis of bridge is done by using Midas Civil software package. Various methods of seismic performance assessment from various literatures are explained. The seismic fragility curves at various stages of failure are developed by data from 100 time history analysis done using Midas Civil Software.
