梁-支撑-钢管混凝土柱连接在高风险地区具有良好的抗震性能。针对这种节点的传力机理尚不清楚，缺乏相关研究的现状，本文通过试验和有限元分析，对节点板贯穿梁-支撑-钢管混凝土柱（BBC）节点的受力性能进行了研究。研究了这种节点的破坏形态、强度、刚度、延性和耗能性能。试验结果表明，节点板能有效地将梁端塑性铰从柱面移开，减小梁端与柱面之间的应变集中，显著改善节点的滞回性能;塑性转角能在强度退化20%之前达到至少4%的层间位移角。通过数值模拟和试验验证，分析了焊缝长度和加固方式对结构强度的影响，并提出了改进设计的建议。
Beam-brace-CFT (concrete-filled tubular) column connections provide excellent performance in resisting seismic loads in high-risk areas. However, the load transmission mechanism of this type of connection still remains unclear, and there is a lack of study on it. Therefore, in this paper, the mechanical behavior of beam-brace-CFT column (BBC) connections penetrated by gusset plates was evaluated through experiments and finite element analysis to resolve this issue. The failure modes, strength, stiffness, ductility, and energy dissipation of this type of connection were studied. Experiment results indicated that the gusset plates in BBC (beam-brace-CFT) connections could effectively move the plastic hinge on beam away from the column face, reduce the strain concentration between the beam end and column face, and notably improve the hysteretic behavior; the plastic rotation was able to achieve at least 4% story drift angle before 20% strength degradation. Numerical studies were carried out and validated by experiment results, and then the influence of the weld length and strengthening methods were investigated; some improvement of design suggestions was proposed.
