摘要
利用大型有限元通用软件ANSYS/LS-DYNA及其并行运算功能,提出了一种大跨度斜拉桥在地震作用下考虑SSI效应的三维整体时程反应分析方法,比较了考虑桥梁结构线性和非线性两种情形的计算结果,并对其计算效率进行了探讨。
By using of finite element software ANSYS / LS-DYNA and its parallel computing function,a 3-D seismic response analysis method for long-span cable-stayed bridge considering soil-structure interaction is presented in this paper.The calculated results with the linear and nonlinear bridge material are compared,and calculation efficiency of both cases are also discussed.
