摘要

摘要: 提出一种钢管混凝土柱与钢筋混凝土梁的新型节点形式。在钢筋混凝土梁与钢管混凝土柱连接区，钢管局部开矩形孔、节点区域钢管加强，使钢筋混凝土梁中的纵向钢筋直接伸入节点，节点混凝土与梁中混凝土成为整体，方便施工且保证了节点刚度。通过4个节点试件的试验，研究节点的破坏过程、破坏形态和耗能性能。研究结果表明：节点的滞回曲线饱满，节点破坏由梁的破坏引起，直至节点达到极限状态，节点尚未破坏，证实了这种节点的可行性，且满足强柱、弱梁、节点更强的抗震设计原则。

Abstract: A new type of concrete-filled steel tube(CFST) column-RC beam joint was presented in this paper.In the CFST column-RC beam connecting zone,the out steel tube of CFST column locally opened rectangular hole and stiffened,the longitudinal reinforcing bars in RC beam stretched into the joint.The concrete was monolithically cast in the region of the beam,the column and the joint.The construction of joint was simplified and the joint stiffness was strengthened.The wasted energy behaviour,failure process and the failure mode of the specimen members were studied by experiments.The studies showed that the hysteretic curves of the joint had plump shuttle shape and the joint did not fail when the specimen was in limit state,while the beam was damaged.The feasibility of the joint in the static load was proved.The joint can meet the seismic design principles ofstrong column,weak beam and stronger joint.
