预应力斜拉网格结构的非线性静力分析

Nonlinear static analysis for prestressed cable-stayed truss structures

对预应力斜拉网格结构的线性和非线性进行了对比分析。分析结果表明:当斜拉索跨度较大或垂度比较大时,不宜忽略斜拉索的非线性影响,应选用合理的方法进行非线性分析,综合考虑斜拉索由于自重垂度对刚度和索力的效应。

The linear and nonlinear analytical results of the prestressed cable-stayed truss structure are compared in this paper. Results showed that the nonlinear effect of cables in large span cable stayed structure should be taken into consideration with appropriate nonlinear analysis method.
