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。
The mechanical properties of steel-reinforced concrete filled steel tubular columns and steel shaped steel beam joints were studied. By using the large-scale finite element analysis software ABAQUS, the displacement loads of the steel-reinforced concrete column-I-beam spatial joint at different beam ends were analyzed. Pressure ratio and mechanical strength under the grade of steel. Through the finite element simulation, the hysteresis curve and the skeleton curve under different parameters were obtained. Based on the obtained curves and data, the mechanical properties of the joints were analyzed in depth.
