【提要】通过千斤顶对索网施加预应力后，索网中预应力分布是已知的。如果边界结构的刚度相对悬索不是无限大，就必须考虑边界结构变形的影响。针对这一情况，提出一种采用大型通用有限元软件ANSYS进行建模的方法。两个算例的计算结果表明，方法是正确的，且操作方便、快捷，可以满足实际工程的需要。

Modeling Analysis of Cable Networks with Flexible Supports/Chen Bilei, Nie Jianguo(Department of Civil Engineering,Tsinghua University,Beijing 100084,China)
Abstract:When prestressed,the cable networks deform together with flexible supports.The
 error will be noticeable without considering the effects of flexible supports.The objective is to present a novelty modelling method using commercial FEA software ANSYS.The results show that the method proposed  is accurate and convenience.
Keywords:ANSYS; cable networks; finite element modeling; flexible supports
