针对传统梁柱节点及混凝土剪力墙-钢梁铰接节点构造复杂、施工难度大等缺点,并结合某工程实际情况,设计了新型梁柱混合节点及混凝土剪力墙-钢梁铰接节点,进行了缩尺构件抗震性能试验。试验表明,两种新型节点均发生梁端破坏,能达到强节点弱构件的抗震要求。通过有限元分析进一步掌握其受力特性,并通过有限元变参数分析研究了梁柱节点承载力的影响因素,结果表明,对梁柱节点承载力影响最大的是内隔板,其次为内埋T柱;内隔板相同的条件下,内埋T柱埋深比T柱高度对承载力的影响更为明显。
Aiming at the shortcomings of the traditional beam-column joints and the concrete shear wall-steel beam hinge joints, the new type of beam-column hybrid joints and the concrete shear wall-steel beam hinge joints are designed according to the complicated construction and the difficult construction. Seismic performance test of scale structure. Experiments show that both new types of nodes have the failure of beam ends, which can meet the seismic requirements of weak joints with strong nodes. Through the finite element analysis to further understand its force characteristics, and through the finite element analysis of variable parameters of the bearing capacity of beam-column nodes, the results show that the most important load-bearing capacity of beam-column joints are internal partitions, followed by embedded T column; Under the same condition of inner partition, the effect of embedding depth of T-pillar over T-pillar height on bearing capacity is more obvious.
