In this thesis, the seismic fragility, seismic hazard and seismic risk of reinforced concrete continuous girder bridges have been systematically studied in the new generation of performance-based earthquake engineering ( PBEE ) initiated by the Pacific Earthquake Engineering Research(PEER) Center ( PEER ) in the United States. 本文以美国太平洋地震工程研究(PEER)中心(PEER)提出的基于性能的地震工程为框架,对钢筋混凝土连续梁桥的地震易损性、地震危险性以及地震风险进行了系统的研究。
