seismic fragility assessment of bridges: a state of art review

In recent years, one of the ways to investigate the vulnerability of bridges is to use fragility curves, which can have many applications before and after earthquake occurrence. these curves are used to assess seismic hazard, prioritize structural rehabilitation, crisis management planning, and multi-risk approaches for lifeline structures in different naturalhazardous zones. also, to estimate the amount of post-earthquake damage which is a prerequisite to ensure continuous transport facilities, emergency and evacuation routes. this paper investigates the practices and methodologies for assessing seismic vulnerability of bridges in regions exposed to high seismicity.
