摘　　要：T型钢连接具有造价低、安装方便等优点,是刚度最大的半刚性连接之一。为了研究T型钢连接整体钢框架的抗震性能,进行了一个两层单跨单开间钢框架模型的拟动力试验,研究了T型钢连接钢框架在El Centro波和宁河天津波作用下节点区域的应变变化、层间位移反应和荷载反馈,分析了钢框架在弹性范围内的变形能力、承载力和抗震能力。试验结果表明,T型钢连接钢框架在弹性范围内具有较好的变形能力、承载能力及良好的抗震性能。研究结论可供工程应用参考。T steel connections is one of semi - rigid connection with low cost and convenient installation and largest stiffness. In order to study the seismic performance of the whole steel frames with T steel connection, pseudo-dynamic test for a single span and one bay two storey steel frame model was carried out, the strain changes,interstorey displacement and load feedeack in joint region of T steel connection steel frame under the action of E1 Centro wave and Ning he Tianjin wave were researched to analyze the deformation , bearing and aseismic capacities of the steel frame within elastic range. The test results show that the T steel connection steel frame has better deformation, bearing capacities and seismic performance within the elastic range. The conclusions may give a reference to engineering application.
