摘要

运用大型有限元通用软件ANSYS/LS-DYNA及其并行运算功能

进行了考虑土-结构相互作用的大跨度斜拉桥地震反应分析。考虑混凝土、土介质和悬索材料的非线性与考虑材料线弹性的计算结果比较表明

考虑材料非线性情况时

由于进入塑性阶段后的能量耗散

内力比考虑线性情况时小;而进入塑性阶段后

结构刚度变小

运动量要比考虑线性情况时大。

Abstract

In this study

the large-scale finite element software——ANSYS/LSDYNA

and its parallel computing function were used to analyze the earthquake response of a large-span cable-stayed bridge with soil-structure interaction.Meanwhile

the material nonlinearity of concrete

soils and cables was considered in the finite element analysis.The results are as following: First

internal forces are less in the case of material nonlinearity than those in the pure flexible study

which is due to energy dissipation at plastic stage;second

the displacement was larger in the case of material nonlinearity than those in the pure flexible study

that is because stiffness reduction at plastic stage.
