摘　　要：钢筋混凝土异形柱结构具有与普通钢筋混凝土矩形柱结构不同的特性,其抗震性能是结构工程领域很关注的问题.本研究设计制作了一榀1/3缩尺的两跨三层的异形柱框架模型,通过低周反复荷载作用下的模型试验,分析研究了其延性、耗能能力等抗震性能.试验分析结果表明,试验的异形柱框架具有较好的延性、耗能能力.The difference between the behavior of the RC structures with special-shaped columns and of the RC structures with conventional rectangular columns focuses civil research＇s attention on its seismic performance. For the purpose of further investigation on its seismic performance of such structure, a two-span and three-story RC frame model with special-shaped columns was designed for 1/3 scale. Based on experiment of the frame model under low-reversed cyclic loading, ductility and energy dissipation are studied systematically. And studies show that the ductility and energy dissipation of the RC frame with special-shaped columns are very good.
