Overview of bridge structure damage criterion under seismic action

In order to reduce bridge project under the effects of earthquake damage, it is necessary to bridge structure under earthquake effect of performance evaluation and comparison, this one of the main thing is that the failure criterion determination. So far, domestic and foreign scholars have made numerous earthquake Failure Criteria for bridge structure, which have a wider application based on the ductile deformation, strength and energy-based guidelines and parameters of energy and ductile deformation of the destruction of two-parameter Failure criteria. This paper makes a summary of the criteria's history and merits.
