摘　　要：本文建立了分析蒙皮支撑的钢构件静力性能的有限元方法．该方法将钢构件离散成空间薄壁梁柱单元，将蒙皮离散成等效的正交各向异性的壳单元，并将钢构件与蒙皮之间的连接件作为连接单元．本文又用所建立的有限元方法对一些实验模型进行了分析．并将计算结果与试验结果进行了比较，二者在线性阶段吻合较好．说明本文建立的方法可以有效地分析蒙皮支撑的钢构件．A finite element method for static analysis of diaphragm-braced steel members is presented in this paper.In this method,the steel member is treated as space thin-walled beam-colunm element,the steel diaphragm is subdivided and simulated as equivalent orthotropic shell elements and the connector Which connectS steel member and diaphragm is modeled by the connection element.By this method,several examples are analysed. The results show that the method iseffective.
