［提要］ 通过对钢框架梁柱高强螺栓连接节点在循环荷载作用下的拟静力试验,分析了各类连接的刚度、承载能力、延性系数和能量耗散机制，并讨论了剖分T型钢连接、顶底角钢腹板双角钢连接和顶底角钢连接的差别。试验结果表明，T型钢翼缘厚度是影响剖分T型钢连接节点性能的主要因素；在计算顶底角钢腹板双角钢连接的连接刚度和抗弯承载力时，应考虑双腹板角钢的影响。

Abstract:The pseudostatic force test of semirigid connections with bolt in steel frame under cyclic loading was carried out to obtain the hysteretic behavior. The rotational stiffness, carrying ability, ductility coefficient and energy consumption mechanism were analyzed,and the differences of three types of connection were discussed. According to the results of test, it is shown that the thickness of T type steel flange is the main factor affectin
g the connection behavior and the effect of web angle should be taken into account when calculating the rotational stiffness and the carrying ability of the topbottom angel with double web angel connections.
