悬索结构非线性分析的滑移索单元法

A nonlinear analysis method with sliding cable elements for the cable structures

本文提出了一种悬索结构存在滑移单元时的非线性计算方法，利用文献［１］提出的五节点曲线索单元有限元基本方程，建立了滑移单元非线性分析的基本计算理论、方法及公式，并进行了实例计算，结果表明，本文方法是行之有效的，可供悬索结构设计、施工时参考。

This paper presented a nonlinear method for the cable structures in which the sliding cable elements exit. Using the finite element modle with five node curved cable elements presented in reference , the author established the calculation theory, formula and method, and used this model to compute one example, the results showed that this method led to good presicion and could meet the need of the engineering. The model presented in the paper can be applied in the design and construction of the cable structures.
