摘　　要：为了节约机时及内存,对剪切膜单元用于模拟内填钢筋混凝土剪力墙板的可行性进行了研究。设计了3个钢框架内填钢筋混凝土剪力墙(SRCW)结构;采用ANSYS软件,用剪切膜单元(shell28)和平面应力单元(plane42)模拟内填墙板,对SRCW结构进行了弹性内力分析,评估了剪切膜单元模型与平面应力单元模型计算结果的差异;分析了结构层数和墙板宽度对上述两种有限元模型计算结果的影响。In order to cut the calculating time and the memory of computer,the paper presents the feasibility of the shearing membrane element used to simulate the infilling reinforced concrete wall.Three specimens of the steel frame filled reinforced concrete shear wall(SRCW)are designed,and the elastic internal force analysis is made to the SRCW structure by use of the stimulated infill walls of the plane stress element and shearing membrane element based on the ANSYS,the differences between the plane stress element model and the shearing membrane element model are assessed,and the effects of the design parameters such as the number of stories and the width of the infill wall on the SRCW behavior are analyzed.
