摘　　要：本文通过对一种新型钢管混凝土柱 -钢筋混凝土梁节点抗震性能的低周反复荷载试验研究 ,对轴力对该种节点的抗震性能的影响进行了详细的讨论 ,得出了轴力使节点的抗震性能降低的结论 ,并分析了这种现象出现的原因。In this paper, the effect of axial force on seismic behavior of a new type of joint between CFRT tubular columns and RC beams, was experimentally studied. The results of this experimental investigation indicate that the presence of axial force on the column has a detrimental effect on the earthquake resistant capacity of this type of joint. The causes of this phenomenon are also analyzed at the end of this paper.
