| 摘 要： | 对一座大跨度悬索桥进行了地震反应谱分析和线性、非线性的地震时程分析,并在此基础上对该桥进行了抗震性能验算.反应谱分析考虑了周期和阻尼比调整,时程分析时考虑了地震动空间变异性的影响,非线性分析考虑几何刚度变化、大位移以及梁柱效应的影响.抗震性能验算分为强度验算和位移验算.

| Abstract: | The seismic response analysis of a long-span suspension bridge is undergone by means of the seismic response spectrum method and the linear/nonlinear seismic time-history dynamic method. The adjustment of period and the damping are taken into account in the seismic response spectrum method, and the spatial variation of seismic ground motions is considered in the linear/nonlinear seismic time-history dynamic method. The seismic performance evaluation concludes the strengths and the displacements. The geometry stiffness variety, large displacement and the effect of girder-column are reckoned in the nonlinear seismic time-history dynamic analysis. |
