摘　　要：从框架支撑等效刚度和层间位移基本原理出发,以鹤壁某煤矿六层钢框架办公楼工程实例为背景工程,通过改变支撑在结构平面内的布置位置和增加支撑数量等,对结构层间位移、层间位移角进行计算对比分析。研究支撑布置对钢框架结构抗侧移性能的影响,探讨支撑布置的影响规律,为多层钢框架结构的设计提供理论参考。Support from the basic principle of the framework of equivalent stiffness and the layer displacement instance of a Hebi coal mine six-story steel frame office building project, the displacement on the structural layer, and the layer displacement angle are calculated and comparative analysisod and then studied the influence of bracing kinds on the lateral stiffness of the multi--storey steelframes to explore the influence of the layouts of bracing by changing the layout of the bracing and increase the number of bracing. A reference for the design of multi-storey steel frame structure is provided.
