| 摘 要： | 悬索结构作为一种柔性受拉结构,在工程中有着广泛的应用。单根悬索在外荷载作用下的受力性能较为简单,但是当大量大跨度悬索相互联结组成群索体系时,对其位移和内力的预测则是一个相当复杂的问题。以某气象塔工程为例,运用有限元分析软件ANSYS,对双向正交悬索组成的群索结构进行找形分析,并计算其在风荷载作用下的位移和应力,分析其位移和应力的变化规律,计算结果较为精确,且与实际符合较好。

| Abstract: | As a kind of flexible tension structure, suspended-cable structure has a wide range of applications on the project. But it＇s more difficult to forecast the displacement and internal forces in the long-span suspended cable group structures. Based on a meteorological tower project, a cable group structure model was analyzed using finite element analysis software ANSYS. The variation rule of displacement and stress under wind load was reached through the form-finding analysis of cable structures. The result was more accurate, and in line with the actual. |
