摘要
通过对三榀普通钢筋混凝土框架、钢支撑框架和塑性耗能支撑框架单元１／３比例模型在低周反复荷载作用下进行对比试验，研究三类不同型式的钢筋混凝土框架结构的破坏形态、位移延性系数、强度退化与累计耗能等抗震性能指标。
Through comparative tests of low cycle loading on three one third scale models of ordinary RC frame,steel braced RC frames with and no plastic damping device,the failure pattern and the aseismic behaviour indexes about coefficient of ductility,degeneration of strength and stiffness,and accumulating energy dissipation of test models of three kinds are studied for the sake of deeper theoretical analysis and engineering design of steel braced RC frames with plastic damping devices.
