| 摘 要： | 大型通用软件在分析复杂桥梁结构时,在某些桥梁专业功能上有所欠缺。针对ANSYS难以直接准确施加斜拉桥索力的问题,讨论了ANSYS中施加索力的几种方法,提出了一种基于循环迭代的方法,通过实例验证该方法是准确、可靠的。

| Abstract: | When used to analyze complicated bridge structures, the large general-purpose finite element procedure ANSYS has some flaws. In order to solve the problem of the accurate exertion of cable forces of cable-stayed bridges by ANSYS, we suggest some methods which are based on circulate iteration in this paper. It has been proved by practical projects that the methods are accurate and reliable. |
