Abstract EN
In order to evaluate the seismic vulnerability of a railway bridge, a nonlinear finite element model of typical three-span continuous beam bridge on the Sichuan-Tibet railway in China was built.
It further aimed at performing a probabilistic seismic demand analysis based on the seismic performance of the above-mentioned bridge.
Firstly, the uncertainties of bridge parameters were analyzed while a set of finite element model samples were formulated with Latin hypercube sampling method.
Secondly, under Wenchuan earthquake ground motions, an incremental dynamic method (IDA) analysis was performed, and the seismic peak responses of bridge components were recorded.
Thirdly, the probabilistic seismic demand model for the bridge principal components under the prerequisite of two different kinds of bearing, with and without seismic isolation, was generated.
Finally, comparison was drawn to further ascertain the effect of two different kinds of bearings on the fragility components.
Based on the reliability theory, results were presented concerning the seismic fragility curves.
