摘　　要：为了研究不同框格形式对网格框架墙体的抗震性能的影响,在试验基础上利用ANSYS有限元软件对不同肋梁肋柱数目的网格框架墙体进行了非线性数值模拟,对该结构的承载能力和破坏形态等抗震性能进行了综合分析.结果表明:肋梁纵筋在传递水平荷载方面的贡献较大,因此设计时可考虑适当加大肋梁配筋;若墙体发生整体弯曲破坏,则肋柱数量较多的墙体承载力较大,但是变形能力相对较小.In order to study seismic performance for the grid-mesh frame wall of different frame space,this paper did ANSYS finite element analysis for the grid-mesh frame wall with different number rib beams and rib columns based on the experiment,comprehensive analyzed the structure's seismic performance such as bearing capacity and failure form,the results show that for the contribution on the wall shear bearing capacity,rib column is greater than the rib beam;If the wall occurred the whole bend destructive,the more rib columns can bear bigger capacity,but the deformation ability is relatively small.
