Abstract: Fulfilling the strength analysis of glass curtain wall with mullion-supporting at the action of combined loads by the finite element analysis software named ANSYS. By the calculation of glass curtain wall with mullion-supported which be constituted of beam element and shell element, then we could obtain the values of deflection and stress of every structure element correctly. Of course, we can also provide theory foundation for improving mechanical properties of total system. The calculation results show that the maximum values of stress and deflection of steel structure are 105.758 MPa and 14.156 mm corresponding for this project in all kinds of combined loads. It also be in favor of curtain regulation so that realize cutting optimization of design process. As a result of all above, this analysis method save cost of product and create more profits for curtain company.

摘要： 　    利用ＡＮＳＹＳ软件对框支承玻璃幕墙在受组合载荷作用时进行了结构有限元强度分析。通过对由梁单元和板单元组成的框支承玻璃幕墙进行分析、计算，可以准确地得到各个构件单元的变形及应力大小，从而为改善系统的力学性能提供了理论依据。计算结果表明：在多种建筑载荷的组合作用工况下，本方案中钢结构龙骨的最大的强度应力值和刚度变形值分别为１０５．７５８ＭＰａ和１４．１５６ｍｍ，完全满足幕墙规范的许可值要求。这样经过有限元的仿真在满足了工程安全的同时，更有利于设计过程中的优化下料，进而节省成本，为幕墙公司创造更多的效益。
