研究了由带钢筋混凝土板的钢管混凝土柱与钢梁组成的组合节点的抗震性能。进行了4个内部节点和2个外部节点的试验,柱顶承受恒定轴力,梁端承受循环荷载。主要参数有:节点形式,柱顶轴力大小及梁截面构造形式。对能反映组合节点韧性、强度退化、耗能能力等抗震性能的几个指标进行分析,结果证明组合节点的抗震性能非常好。
The seismic behavior of composite joints composed of CFST columns with steel beams and concrete beams is studied. Four internal nodes and two external nodes were tested. The top of the column was subjected to constant axial force and the beam end was subjected to cyclic loading. The main parameters are: node form, column top axial force size and beam cross-section structure. Several indexes which can reflect the seismic performance of composite joints such as ductility, strength degradation and energy dissipation capacity are analyzed. The results show that the seismic performance of composite joints is very good.
