摘　　要：该文通过ABAQUS有限元软件对单层单跨的方钢管混凝土柱-H型钢梁框架进行有限元模拟计算。按1∶4缩尺建立框架模型,施加低周往复荷载作用,分析框架的受力过程;改变节点形式,分析不同节点刚性框架的破坏形式、滞回曲线和骨架曲线。结果表明,使用新节点的钢管混凝土框架具有较好抗震性能;与刚性连接的框架相比,框架能够有效保证节点域安全可靠,充分发挥梁的耗能能力。In this paper,the finite element simulation of single-story single-span concrete-filled square steel tubular column-H-shaped steel beam frame is carried out by ABAQUS finite element software.The frame model is established according to 1:4 scale,low cyclic load is applied to analyze the stress process of the frame,and the failure forms,hysteretic curves and skeleton curves of rigid frames with different joints are analyzed by changing the joint form.the results show that the concrete-filled steel tubular frame with new joints has better seismic performance,and compared with the frame with rigid connections,the frame can effectively ensure the safety and reliability of the joint domain and give full play to the energy dissipation capacity of beams.
