Assessment of vulnerability of bridges are important because when earthquake happen, the bridge must be safe for transporting people. For reaching that purpose civil engineering has made experimental and fundamental way to access result to having the best judge and modeling the bridge to have the best seismic response . For reaching damage of bridge, fragility curve is a useful tool and best way for it. Seismic response of bridge from analyzing is way for drawing fragility curve. In this research, fragility curve will present for three concrete span bridge. All part of bridge such as column and abutment have created by correct elements and materials that has shown in here. Different response will show here such as abutment response and deformation of pile and response of seismic for fragility curve. IDA test will use in this research and for reaching that need earthquake record.
