摘要:
由于目前桥台性能对整个桥梁结构地震易损性影响的研究较少,本文对考虑桥台性能的连续梁桥地震易损性进行研究。以一典型三跨连续梁桥为例,分别建立了有、无桥台两种情况下的有限元模型;根据四类场地从PEER(Pacific earthquake engineering research center)强震数据库中各选取100条地震波来模拟地震动的不确定性,并组成“结构—地震波”样本对;采用OpenSees对结构进行非线性时程分析后得到构件响应,并定义了各个构件的四种极限破坏状态;采用可靠度理论得到各个构件的地震易损性曲线。研究表明:桥台对构件的地震响应有显著影响,若不考虑桥台作用将会使其他构件的损伤概率明显增大;且在同一场地条件下,墩柱最易损伤,滑动支座次之,而桥台最不易损伤。
