【摘要】：正利用OpenSees軟件對一座主跨為420m的斜拉橋建立有限元模型,分別進(jìn)行了僅考慮失相干效應(yīng)、考慮失相干效應(yīng)和行波效應(yīng)、考慮失相干效應(yīng)和場地效應(yīng)以及綜合考慮失相干效應(yīng)、行波效應(yīng)和場地效應(yīng)這4種非一致激勵(lì)情況下的易損性分析.結(jié)合聯(lián)合概率地震需求模型和蒙特卡羅方法抽樣獲得了基于構(gòu)件的體系易損性曲線.考慮地震動(dòng)空間效應(yīng)的飄浮體系
[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
