摘　　要：通过有限元分析软件ANSYS分析了集中力作用下的墙体的竖向应力的分布及扩散情况,并将分析结果与按受压构件和局部受压构件计算而得的承载力进行了比较,在此基础上对集中力作用下的墙体的计算截面宽度和承载力计算提出了建议。Using finite element analysis soft ANSYS to analysis the distributing and diffuse of vertical stress of walls subjected to a concentrated load,and we also compare the analysis results with the load capacity calculated through compressed member and partially compressed member. Finally some suggestions on the width of calculation section and load capacity of walls subjected to a concentrated load are given.
