摘　　要：目前关于半刚性连接性能的分析主要集中在梁与柱强轴连接上,而对于梁与柱弱轴连接的研究并不多。通过顶底角钢与H型钢柱弱轴连接节点的伪静力试验,分析了两种弱轴顶底角钢连接节点在循环荷载作用下的受力性能和破坏机理。研究结果表明,该连接节点是典型的半刚性连接节点,具有明显的非线性性质,在地震荷裁作用下具有稳定的滞回性能和良好的耗能性能。Research on beam-to-column semi-rigid connections is mainly focused on major axis connections at present, Tests and research on steel beam-to-column minor axis connections are still limited. Through pseudo-static tests of minor axis semi-rigid connections with angles, mechanical performance and damage mechanism on two types of minor axis semi-rigid connections with top and seat angles were analyzed systematically. The results indicate that the connections are typical semi-rigid connections with nonlinear properties and have good hysteretic and energy dissipation properties.
