| 摘 要： | 综合考虑几何及材料非线性的影响，利用有限元分析软件ANSYS，建立了吉林市临江门独塔斜拉桥实体单元有限元模型，对斜拉桥关键部位进行了非线性静力分析，结果表明，考虑材料非线性影响后塔梁固结处及主梁的应力和位移平均增大10％，索应力最大相差20％，因此对于中小跨度斜拉桥应考虑材料非线性的影响。

| Abstract: | Taking into account material and geometry nonlinearity,a finite element model of Jilin Linjiangmen cable-stayed bridge with single tower is presented by ANSYS,and key parts of cable-stayed bridge is studied through nonlinear static analysis.The results show that the stress and displacement of key parts are averagely larger at about 10%,which calculates material nonlinearity and the difference max reaches 20%in the cables.So material nonlinearity effects are very outstanding to the middling span cable-stayed... |
