摘　　要：选取ANSYS有限元软件采用整体式模型建模方法建立建筑模型,选取SOLID65单元建立模型砂浆与砌块部分,SOLID65单元可以模拟建筑墙体中钢筋混凝土的开裂、塑性形变等力学性能,实现建筑机械载荷的有效仿真。仿真结果表明,施加于墙体机械载荷大小为86.9 kN时,墙体出现开裂变形;施加于墙体机械载荷大小为115.7 kN时,墙体出现破坏坍塌情况。ANSYS finite element software is selected to establish the building model using the integral model modeling method,and the SOLID65 element is selected to establish the model mortar and block parts.The SOLID65 element can simulate the mechanical properties of the reinforced concrete in the building wall such as cracking and plastic deformation,and realize the mechanical load of the building.Effective simulation.The simulation results show that when the mechanical load applied to the wall is 86.9kN,the wall will crack and deform;when the mechanical load applied to the wall is 115.7kN,the wall will collapse and collapse.
