摘　　要：应用Push-Over方法的2种荷载形式,对一个纯钢框架结构体系在地震作用下的弹塑性性能进行了分析.通过对其变形性能和塑性铰规律的研究,得到纯钢框架体系的抗震性能,还通过对其塑性铰发生位置和发生顺序规律的研究,得出纯钢框架结构的薄弱层和最不利位置,为纯钢框架结构体系的优化设计提供了理论基础和前提条件,同时也有利于纯钢框架结构体系在抗震设防地区的推广.The elastoplastic performances of a pure steel frame are studied by two load patterns of pushover method, and the structure＇s anti-seismic performances in the deformation properties and law of the plastic hinge are known. In the meantime, the weakest layer and the most unfavorable position of the pure steel frame are finally found, thus providing a theoretical basis and the prereguisite for the optimal design of the frame. It can help popularize this structural form in seismic areas.
