摘　　要：半刚性连接具有施工方便、受力合理等优点,已逐渐应用在工程中。通过一个两层T型钢连接平面钢框架模型的拟静力试验,研究了此框架中剖分T型钢连接的变形情况、空间钢框架的耗能特性、变形特征、塑性铰出现顺序、钢框架破坏模式等,从而得到半刚性连接平面钢框架的抗震性能。结果表明:T型钢连接钢框架具有较好的变形能力和承载能力,非常适合在地震区中应用。With the advantages of convenient construction,reasonable stress and so on,the semi-rigid connection has been applied in the practical engineering. Through the low cyclic loading test of a two-layer steel frame model,which was connected by T-stub steel connctions,the deformation of the dividing T-stub steel connections,the energy dissipation,the deformation behavior,the sequence of plastic hinges occurring and the failure modes of the steel frame were investigated,so as to obtain the seismic performance of the steel frame with semi-rigid connections. The results indicated that the T-stub steel connection had preferable deformability and bearing capacity,which could be widely applied in the seismic regions.
