摘　　要：为了得到一种受力较为合理的装配式钢结构开洞墙体设计,在三种工况荷载作用下首先通过拓扑优化设计,给出材料分配较为合理的新型结构形式,然后通过尺寸设计,得到受力比较均匀的构件形式以及尺寸,最后通过屈曲分析,保证开洞墙体的稳定性。最终得到的新型开洞墙体的结构满足刚度、强度及稳定性的要求并具有较好的抗震性能。In order to get a kind of force reasonable open hole in the wall design,prefabricated steel structure under working condition of three kinds of load first by the topological optimization design,give the new structure form of the material allocation more reasonable,and then through the size design,stress is homogeneous form and size of components,finally through the analysis of the buckling,can guarantee the stability of open hole in the wall.Finally,the new type of wall structure meets the requirements of stiffness,strength and stability,and has good seismic performance.
