摘　　要：研究钢骨方钢管混凝土柱与工字形钢梁节点的力学性能,利用大型通用有限元分析软件ABAQUS分析了钢骨方钢管混凝土柱-工字钢梁空间组合节点在不同的梁端位移荷载、轴压比和钢骨强度等级下的力学性能。通过有限元模拟,得到不同参数下的滞回曲线和骨架曲线,根据得到的曲线和数据,对节点的力学性能进行了深入分析。Using the finite element analysis software ABAQUS,the mechanical properties of the joint of square steel tubular columns filled with steel-reinforced concrete and I-shaped steel beam was studied and analyzed under different parameters,including the load-displacement for beam end,the axial compression ratio and steel strength. The hysteretic curves and skeleton curves of the experiments under different parameters were obtained through the finite element simulation. According to the curves and data,this paper analyzed the mechanics properties of beam-column joints deeply.
