Translated Title

Model parameter comparison of bridge seismic vulnerability based on PSDM and IDA methods

Translated Abstract

Taking　a　typically　simply　supported　girder　bridge　in　the　Wenchuan　region　as　an　example,　a　3D　baseline　nonlinear　finite　element　model　of　the　bridge　structure　was　built　by　OpenSees　platform.A　set　of　nonlinear　seismic　response　analyses　for　the　bridge　samples　were　preformed　in　which　the　uncer　tainty　of　ground　motion　and　bridge　parameters　are　considered,　and　the　seismic　vulnerability　models　of　the　bridge　components　and　system　were　built　by　PSDM　and　IDA　methods.The　physical　interpretations　of　the　vulnerability　modal　parameters　were　introduced.The　model　parameters　of　the　seismic　vulnerabil　ity　results　by　different　methods　were　compared,　and　the　causes　of　difference　and　improvement　meas　ures　were　analyzed　and　discussed.
