【摘要】 文章基于滑移耗能思想，提出一种可以控制损伤并实现震后修复的多腔钢管混凝土T形柱H型钢梁装配节点；通过改变上下连接板件的厚度与腹板连接方式改变连接处刚度，对6个试件进行模拟分析，得到相应的滞回曲线、骨架曲线、力学性能指标及转动能力。研究结果表明：合理控制翼缘连接盖板厚度可以转移塑性铰、保护节点核心区，使节点具有及时修复的功能；腹板连接件可以提高节点的刚度、承载力及延性；腹板连接件不宜过大，应该与翼缘保持一定的缓冲距离。更多还原

【Abstract】 In order to control the damage and realize the post-earthquake repair, an assembled joint of multi-cavity concrete-filled steel tube T-column H-beam is proposed based on the idea of slip energy dissipation. By changing the thickness of the upper and lower connecting plates and the connection mode of the web to change the joint stiffness, the hysteresis curve, skeleton curve, mechanical indexes and rotational capacity of six specimens were obtained through the simulation analysis. The results show that the reasonable control of the thickness of flange connecting cover plates can transfer the plastic hinge and protect the core region of the joint, so the joint can be repaired in time. The web connector can improve the stiffness, bearing capacity and ductility of the joint. The web connector should not be too large and should maintain a certain buffering distance from the flange.更多还原
