摘　　要：本文通过普通钢筋混凝土框架、耗能支撑钢筋混凝土框架结构１／８比例模型的地震模拟振动台对比试验，研究两类框架结构在地震作用下的破坏形态和动力特征，揭示了耗能支撑钢筋混凝土框架结构良好的抗震性能；对试验模型进行了弹塑性时程分析，理论分析和试验结果符合较好；结合扬州电厂二期主厂房框排架结构，研究了其纵向框架结构采用耗能支撑体系时结构的抗震性能。Three reinforced concrete frames,including two with energy dissipation bracings and the other with common bracings,have been tested under reversed cyclic loads for comparison The mechanic characterisitcs,failure modes,ductility and energy dissipating ability of these kinds of frame structures are studied The results show that the frame with energy dissipation bracings has better aseismic behavior than the frame with common bracings and can be proposed for practical use
