摘要:
为对比空间位置不同的型钢混凝土（SRC）异形柱框架的抗震性能，各设计1榀边框架和中框架进行低周反复加载试验，获得其破坏形态，分析其滞回曲线、骨架曲线、承载力、延性、耗能能力、刚度和型钢应变等特性．结果表明：SRC异形柱框架符合“强柱弱梁、强构件弱节点”的抗震设计要求，滞回曲线饱满，延性好，耗能能力强；与边框架相比，SRC异形柱中框架具有更高的承载力、更强的耗能能力和更大的初始刚度，但两者的延性比较接近，刚度退化速度相差不大．
Abstract:
In order to compare the seismic performance of steel reinforced concrete (SRC) frames with special-shaped columns at different spatial locations, two models, an exterior frame and a middle frame, were tested under low cyclic reversed loading. The failure pattern were obtained and the mechanical behaviors such as hysteretic loops, skeleton curves, carrying capacity, ductility, energy dissipation, stiffness and shape steel strain distribution were analyzed. Test results show that SRC frame with special-shaped columns satisfies the seismic design principle of “strong column and weak beam, strong joint and weak member”, the hysteretic loops are plump, the ductility is good and the energy dissipation is strong. Compared with the exterior frame, the middle frame has higher carrying capacity, stronger energy dissipation and larger initial stiffness, but the ductility and rate of stiffness degradation is not as great .
