| Abstract: | On the basis of non linear finite element method , fundamental equation and solution of pneumatic membrane structure finite element analysis are put forward. It is to use minimum bi multiplication to solve the prestress distribution of pneumatic structure under initial internal force. This paper also makes an analysis of membrane structure internal force under external force. |
