| 摘 要： | 通过8个钢管混凝土(CFST)柱-钢筋混凝土(RC)梁钢筋环绕式节点在低周往复荷载作用下的试验,对其在不同轴压比下的开裂破坏模态、滞回特征、剪切变形、钢筋和钢牛腿变形、延性和耗能性能等进行系统研究。试验结果表明,试验节点的破坏模态均为核心区剪切破坏,圆钢管混凝土柱节点较方钢管混凝土柱节点的滞回曲线饱满,但均能满足现行规范的抗震设计要求。

| Abstract: | Tests on eight concrete filled steel tubular(CFST) column-reinforced concrete (RC) beam joints enclosed by rebars under reversed loading were carried out.The failure patterns,hysteretic characteristics,shear transformation,rebar and steel bracket deformations,ductility and energy dissipation under different axial load levels for joints with circular or square columns are discussed in details.The results indicated that all the joints failed in shear failure pattern.Generally,the hysteretic curves for joints with circular columns were plumper than those with square columns,and the seismic performance of all joints can satisfy current Chinese seismic code requirements. |

| Keywords: | concrete filled steel tube RC beam joint enclosed by rebars low-cycle reversed loading seismic performance |
