摘要
本文以上海市浦江大桥工程设计为背景,研究大跨度斜拉桥设计中,采用具有单边约束性质的辅助墩设计方案的分析方法。对于具有分段线性特性的多折点本构关系系统,通过引入一组控制变量,由参变量变分原理,将其归结为一个线性互补问题进行求解。本文分析方法对分段线性系统极为有效。研究结果,可以为斜拉桥工程设计与改进提供参考。
In this Paper, a method for analyzing cable-stayed bridge with unilateral supports is proposed and applied to the long-span bridge to be constructed in Shanghai. For the systems of multi folded constitutive relation with piecewise linearity, a set of control variable has been introduced. By using the parametric variational principle, it leads to the solution of a linear complementary problem. It is found that the proposed method is particulary suitable for the system of piecewise linearity. Results presented in this paper will be valuable for the engineering design aud improvement of the cable-stayed bridges.
