中文摘要：

为了研究型钢再生混凝土框架的抗震性能,设计了一榀缩尺比为1：2.5的三层两跨型钢再生混凝土框架,对其进行了低周反复水平荷载试验,观察了框架的破坏过程和破坏形态,获得了框架的滞回曲线、骨架曲线,分析了框架的承载能力、刚度、延性、耗能等抗震性能.结果表明：型钢再生混凝土框架结构的破坏属于＂强柱弱梁＂的破坏机制;框架的荷载-位移滞回曲线呈饱满的梭形,具有较好的耗能能力;破坏时试件的整体最大位移角为1/22,正反向平均位移延性系数为4.3,表现出了较好的变形能力和抗倒塌能力。

英文摘要：

In order to investigate the seismic behaviors of steel reinforced recycled concrete（SRRC）frame structure,a 1：2.5 scale model of three-story and two-bay SRRC frame was designed.The low cyclic reversed loading test on this model was carried out,its failure process and pattern were observed,its load-displacement hysteretic loops and skeleton curves were acquired,and its seismic behaviors,such as load carrying capacity,stiffness,ductility,energy dissipation capacity were analyzed.The result of test shows that,the failure mode of the SRRC frame belongs to ‘strong column week beam＇ failure mechanism,its maximum displacement angle is 1/22,and the average displacement ductility coefficient of the frame is 4.3.All these show the good deformation capacity and collapse resistance capacity.
