摘　　要：对5个新型钢管混凝土板柱结构中柱节点的模型试件进行了低周反复荷载作用下的试验研究,分析并评价了不同配筋方式对其破坏形态、滞回特征及延性等抗震性能的影响.试验结果表明:新型钢管混凝土板柱节点在低周反复荷载作用下具有良好的受力性能,其构造方式能够满足“强柱弱板”的抗震设计原则;在柱上板带配置抗冲切箍筋能有效提高节点的抗震性能;无论是否配有抗冲切箍筋,弯曲破坏时节点的塑性变形能力和抗震性能均优于发生冲切破坏的节点.The experiments of five scaled specimens with a novel interior slab-CFST （ Concrete-Filled Steel Tubular） column connection were carried out under low cyclic loading. The effects of different reinforcement arrangements on the failure mode, the anti-seismic behaviors including the hysteresis property and the ductility were then analyzed and evaluated. Test results show that the novel connection is of excellent performance under low cyclic loading, and that the construction form meets the anti-seismic design principles of strong column and weak slab. Moreover, reinforced stirrups in slab strips on the column can effectively improve the anti-seismic behavior of the connection, and, no matter whether the slab strips are reinforced with stirrups, the plastic deformation capacity and anti-seismic behavior of the connection with flexural failure are all better than those of the connection with punching failure.
