- Abstract:
- In this paper,based on a long-span cable-stayed bridge,a finite element model is established by using SAP2000.Based on structural objectives,we studied on calibration method for bridge structure damage.By using collapse vulnerability analysis method which is based on IDA,we analyze the lateral seismic fragility of cable-stayed bridge.Finally,the seismic fragility curves of the main tower can be fitted by using capacity requirement modeling method.The research indicate that under the transverse seismic waves,towers became more vulnerable at the section of top and the bottom of upper tower column.The bottom of mid tower connecting the girder tends to be completely destroyed.
