摘　　要：本文设计了一榀三层两跨的方钢管混凝土框架模型,梁柱节点采用内隔板节点型式。采用拟静力试验方法,对方钢管混凝土框架施加低周反复水平荷载,研究了方钢管混凝土框架内隔板节点的荷载-位移曲线、节点延性、节点破坏机制和破坏特点等抗震性能。研究结果表明,方钢管混凝土框架内隔板节点的抗震性能较好。A 3-floor 2-span concrete-filled steel square tubular frame model was designed. Inner diaphragm joints were used in the frame model. The quasi-static experiments were carried out. By exerting low reversed cyclic loads on the concrete-filled steel square tubular frame, the seismic performance was analyzed, including the load-deformation curve of the inner diaphragm joints in the concrete-filled steel square tubular frame, the joints' ductility, the joints' failure mechanism, the failure characteristics, and so on. The results indicate that the inner diaphragm joints in the concrete-filled steel square tubular frame have good seismic performance.
