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。研究结果表明,T型钢连接钢框架具有较好的变形能力和承载能力,适合在地震区中应用。Featured with the advantages of convenient construction and rational load-carrying capability, the semi-rigid connections have been applied in the practical engineering. Through the pseudo static test conducted on a single across and one bay steel frame model, the paper studies the deformation of the T steel connection, the energy dissipation, the deformation behavior, the sequence of plastic hinges occurring and the failure mode of the steel frame in order to get the anti-seismic properties of the steel frame in semi-rigid connection. As the test results indicated, the T steel connection has preferable deformability and carrying capacity, which could be widely applied in the seismic regions.
