Long-span　continuous　rigid　frame　Bridges　is　major　bridge　type　for　application　of　high　piers,　so　an　in-depth　study　about　its　seismic　performance,　earthquake　damage　and　the　process　of　destruction　has　important　significance.　The　typical　nonlinear　numerical　analysis　model　is　built　for　long-span　continuous　rigid　frame　bridge　with　high　piers　based　on　the　fiber　model.　A　special　Pushover　method　is　proposed　for　nonlinear　analysis　on　the　structure　under　the　earthquake　in　longitudinal　and　transversal　direction　respectively.　Incremental　Dynamic　Analysis　method　is　performed　with　the　nonlinear　dynamic　history　analysis　for　comparison　the　results.　The　failure　law　is　analyzed　by　material　fracture　criterion　with　index　of　strain.　A　typical　continuous　rigid　frame　bridge　with　piers　with　various　heights　suffered　longitudinal　and　transversal　earthquake　is　analyzed,　considering　the　higher-order　effects.　The　applicability　of　Pushover　method　is　discussed.　The　damage　order　and　the　characteristics　of　the　element　are　studied.　The　relationship　between　maximum　displacement　or　maximum　curvature,　with　the　strain　limit　are　discussed.　The　internal　force,　deformation　of　piers,　and　curvature　along　the　high　of　pier　are　analyzed.　©　2012　American　Scientific　Publishers.
