为推广组合梁一复合螺旋箍混凝土柱结构体系，提出了一种梁贯通式的蜂窝组合梁一复合螺旋箍混凝土柱节点，节点核芯区采用双U形箍筋贯穿梁腹板，并在梁上下翼缘位置设置柱短钢板箍．对两个1／2缩尺的蜂窝组合梁一复合螺旋箍混凝土柱节点试件和一个模拟节点核芯区试件进行了低周反复荷载试验．试验结果表明扩张比为1．2的试件在非洞口处出现了钢梁的弯曲破坏，扩张比为1．3的试件同时在洞口和非洞口处同时出现了铜梁的弯曲破坏．提出了节点抗剪承栽力计算公式，节点试件试验值与计算值吻合．两个节点试件的荷栽位移曲线呈理想的梭形，且延性系数分别为4．55和4．30，等效粘滞阻尼系数分别为0．46和0．38，说明节点有良好的抗震性能．

英文摘要：

In order to popularize the structure form consisting of the compostite beam and the compound spiral hoop-reinforced concrete （CSHRC） column, a beam-through-type connection of the castellated composite beam- CSHRC column is proposed. In the core zone of the connection, the U-shaped stirrups cross the beam web, while the short steel plate hoops of column are set at the beam top and the bottom flanges position. Through the low-cycle reversed loading experiments of two 1/2-scaled castellated composite beam-CSHRC column connection specimens and a simulating core zone specimen, it is found that the local buckling failure of the steel beam occurs near the column face for the specimen with an expansion ratio of 1.2 while near the column face and the web opening for the specimen with an expansion ratio of 1.3. Moreover, a formula of the shear capacity of the connection core zone is put forward, and the calculating values based on the formula accord well with the experimental ones. The two 1/2- scaled connection subassemblies both have an ideal spindle shaped load-drift hysteresis curve, and their ductility factors and equivalent viscous damping coefficients are respectively 4. 55, 4.30 and 0. 46, 0. 38, which means that the proposed connection has a good anti-seismic behavior.
