| 摘 要： | 对索网结构的几种常见"找形"方法进行了简要综述。论述了采用几何非线性有限元方法,通过调整支座位移,从而寻求一个与给定的初始预应力及其结构几何控制参数相适应的平衡形状的理论方法,并利用ANSYS有限元软件对常见的索网找形过程进行了研究。算例结果表明,该方法用来确定结构的初始形状是切实可行的。

| Abstract: | A few of methods of cable-net form-finding analysis are summarized briefly.In especial,the support displacement method is discussed,which uses the nonlinear FEM to find the final equilibrium configuration for satisfying the given initial prestress and the boundary condition of the cable net.Several regular cable-net form-finding processes are calculated by applying ANSYS software.The results demonstrate that the methods described above are practicable. |
