| 摘 要： | 总结了目前索系结构分析中应用的索单元有限元模型的种类及其优缺点，通过不同类型的单元对小垂度和中等垂度的悬索问题进行了分析。结论表明，中等垂度内的悬索结构使用直线型单元进行分析可以满足工程要求，使用高精度单元意义不大。

| Abstract: | Various of cable elements and corresponding advantages and disadvantages are generalized and compared with each other. Two typical examples are analysed with different types of elements. The results demonstrate that the straight rod dement can be used to analyse cable structures of medium - scale sag ratio. The straight rod dement can satisfy engineering requirement, multi -node dements are not important and necessary for the engineering computation of cable structures of medium - scale sag ratio. |
