| Abstract: | Firstly, the principle of form-finding analysis of tensile membrane structures is introduced in this paper. Secondly, several mechanical models of the cable element and the membrane element using nonlinear finite element are discussed, and the geometric equations, physical equations and equilibrium equations corresponding are built. In the end, the minimal surface is equilibrium state in form-finding analysis that is presented. |
