摘　　要：为探索建筑钢结构低能耗循环利用技术,研究方钢管柱-矩钢管梁采用榫卯连接、砂浆灌浆阻滑的钢框架节点的抗震性能。对榫卯灌浆节点及传统全焊接节点进行了低周往复荷载试验,对比分析其破坏形态、荷载-位移滞回曲线、延性系数以及极限承载力,并建立有限元分析模型,与试验结果进行对比。研究表明:榫卯灌浆节点在弹性阶段的承载力与全焊接节点相当,但榫卯灌浆节点的极限承载力高于全焊接节点,塑性发展平台更长;榫卯灌浆节点的破坏方式为砂浆磨损挤碎,钢构件损伤小;摩擦耗能效果好,滞回曲线饱满,且震后砂浆易修复。To explore the low energy consumption and recycling technology of building steel structure,this paper studied the seismic performance of steel frame joint with mortise-tenon connection and mortar grouted to resist sliding.The low cycle reciprocating load tests were carried out on the mortise-tenon grouted joint and the traditional welded joint.The failure modes,the force-deformation hysteretic curves,ductility coefficient and bearing capacity were compared and analyzed,and the finite element analysis model was established to compare with the test results.The results show that the bearing capacity of mortise-tenon grouted joint in the elastic stage is equivalent to the welded joint.The ultimate bearing capacity of mortise-tenon grouted joint is higher than the welded joint,and the plastic development platform is longer.The failure mode of mortise-tenon grouted joint is mortar wear and crushing,and the damage of steel members is small.The friction energy dissipation effect is good,the hysteresis curve is full,and the mortar can be easily repaired after the earthquake.
