摘    要:基于增量动力分析方法,通过非线性地震反应分析,得到整体结构的破坏特征和易损位置,分析适用于高墩大跨连续刚构桥的损伤指标.对高墩大跨连续刚构桥进行整体结构的地震易损性分析时,采用应变作为墩柱损伤指标,位移作为支座损伤指标,绘制了基于整体性能的全桥易损性曲线.

关 键 词:高墩大跨连续刚构桥  损伤指标  地震易损性  增量动力分析

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