For cable reinforced membrane structures, gravity was taken into account to find the equilibrium surface.
对考虑重力作用的索膜结构的初始形状确定问题,本文先采用非线性有限元格式得到初始近似曲面,然后在此曲面上考虑索膜的重力,仍采用非线性有限元格式得到最终需要的平衡曲面。
The first kind is to find the minimum surface with identical stress distribution,the second kind is to find the equilibrium surface that satisfies the given boundaries,and the third is the finding of the uniform stress surface that can equilibrate under given surface geometry.
第二类问题是给定边界条件的平衡曲面确定问题，第三类问题是给定曲面几何的最均匀应力分布确定问题。
