Abstract：

The　failure　behavior　and　the　vulnerable　position　of　the　rigid　frame　bridge　are　analyzed　by　nonlinear　response　analysis,　based　on　incremental　dynamic　analysis　(IDA).　The　damage　index,　applying　for　long-span　continuous　rigid　frame　bridge　with　high　pier,　is　studied.　The　seismic　vulnerability　problem　of　the　whole　bridge　is　analyzed　by　fiber　model.　The　strain　was　used　for　damage　index　of　piers.　The　displacement　was　used　for　damage　index　of　bearings.　According　to　the　studies　above,　the　fragility　curves　are　established　based　on　integral　performance　of　the　bridge.
