【摘要】：正利用OpenSees软件对一座主跨为420m的斜拉桥建立有限元模型,分别进行了仅考虑失相干效应、考虑失相干效应和行波效应、考虑失相干效应和场地效应以及综合考虑失相干效应、行波效应和场地效应这4种非一致激励情况下的易损性分析.结合联合概率地震需求模型和蒙特卡罗方法抽样获得了基于构件的体系易损性曲线.考虑地震动空间效应的飘浮体系
[Abstract]:The finite element model of a cable-stayed bridge with a main span of 420 m is being established by using OpenSees software. Only the incoherent effect, the decoherent effect and the traveling wave effect, the decoherent effect and the site effect, and the incoherent effect are considered, respectively.Vulnerability analysis of traveling wave effect and site effect under four non-uniform excitations.Combined with probabilistic seismic demand model and Monte Carlo sampling, the system vulnerability curve based on component is obtained.Floating system considering the spatial effect of ground motion
