介绍了膜结构的发展和组成。依托现有的例子,通过施加预应力,对受压性能和张力进行分析。并利用ANSYS有限元软件,选取平面应力单元SHELL41,对新型建筑体系中的膜结构进行非线性力学分析,通过理论计算和数值比较,得到了数值分析满足工程实践的结论,揭示了这种有限元模型的可靠性和实用性。
The development and composition of membrane structure are introduced. Relying on existing examples, the compressive properties and tension are analyzed by applying prestressing force. The finite element software ANSYS was used to select the plane stress element SHELL41 to do nonlinear mechanical analysis of the membrane structure in the new building system. The theoretical analysis and numerical comparison show that the numerical analysis satisfies the engineering practice. The finite element method Model reliability and practicality.
