摘　　要：本论文利用ANSYS有限元分析程序对梁板复合结构进行在自重以及风荷载作用下的静力分析,模态分析。静力分析时通过给结构整体施加竖向重力加速度研究结构在自重作用下的情况,可以得出:在重力作用下,水平方向应力σx的最大值位于底层楼板的中部柱板交汇位置,位于中间部位柱子的轴力大于位于边角上的柱子。在自重及风荷载作用下,结构自下而上变形增大,且最大变形发生在顶板一角上。In this paper,ANSYS finite element analysis program is used for static analysis and modal analysis of beam slab composite structure under self weight and wind load.In the static analysis,the vertical gravity acceleration is applied to the whole structure to study the situation of the structure under the action of self weight.It can be concluded that under the action of gravity,the maximum horizontal stressσx is located at the intersection of the column and slab in the middle of the bottom floor,and the axial force of the column in the middle is greater than that of the column in the corner.Under the action of self weight and wind load,the deformation of the structure increases from bottom to top and the maximum deformation occurs at the corner of the roof.
