实复及空复式钢管混凝土梁柱节点抗震性能分析

为了对比分析实复式与空复式钢管混凝土柱-钢梁节点的抗震性能,利用有限元软件ABAQUS对实复式钢管混凝土柱-钢梁节点进行了模拟,并与实测试验数据进行了对比.通过建立空复式钢管混凝土柱-钢梁节点模型,完成了实复式及空复式钢管混凝土梁柱节点的抗震性能对比分析.结果表明,实复式钢管混凝土柱-钢梁节点的延性系数、耗能能力、强度退化和刚度退化等抗震性能指标均优于空复式钢管混凝土柱-钢梁节点.

Seismic performance analysis for column-beam joints with solid and hollow multiple concrete filled steel tubes

In order to compare and analyse the seismic performance of column-beam joints with solid and hollow multiple concrete filled steel tubes, the column-steel beam joints with multiple concrete filled steel tube were simulated with the finite element software ABAQUS, and the simulation results were compared with the experimental data. Through establishing the model for the column-steel beam joints with hollow multiple concrete filled steel tube, the comparative analysis for the seismic performance of column-steel beam joints with solid and hollow multiple concrete filled steel tubes was completed. The results show that the seismic performance indexes of column-steel beam joints with solid multiple concrete filled steel tube, including ductile coefficient, energy dissipation capacity, intensity degradation and stiffness degradation, were better than those of column-steel beam joints with hollow multiple concrete filled steel tube.
