摘　　要：通过两榀1/2比例的一跨两层半刚性连接钢框架模型的低周反复荷载试验,研究了框架模型的破坏机制、、出铰顺序、滞回特性、耗能能力等抗震性能。从而得出结论:具有腹板双角钢的顶底角钢连接的钢框架由于节点连接刚度较小,因此框架在侧向力作用下变形较大,但同时此连接也改善了梁柱的内力分布,提高了框架的耗能能力,增加了结构抗震性能。Based on the experiment of two one-second scale, one-bay, two-story steel frame models with semi-rigid connections under cyclic reversal loading, the seismic behavior of the steel frame with semi-rigid connections, including the failure pattern, occurrence order of plastic hinge, hysteretic property and energy dissipation, etc, is investigated in this paper. Some conclusions are obtained for steel frames with top-seat and two web angles connections, that is changed is, the higher distortion occurred in the frames, and the intemal force distribution of beams and columns , and the ductility and seismic energy absorbing capability of the steel frames can be improved effectively
