| 摘 要： | 文章对钢管混凝土(CFST)柱-钢筋混凝土(RC)环梁中节点(JN-1、JN-2)这2个节点在静载和低周反复荷载作用下的试验结果从承载力和变形能力两方面进行分析,并对环梁节点在破坏形态、延性、耗能能力等方面进行研究。试验研究表明,静载试验中,环梁节点在交界处形成塑性铰,向框架梁延伸;低周反复荷载试验中,环梁节点在环梁与框架梁交界处形成塑性铰。环梁节点满足传递梁端剪力和弯矩的要求,塑性铰在框架梁端,节点表现出良好的延性,容易达到"强柱弱梁"的抗震设计目的。 |
| 关 键 词： | 环梁节点 静载 低周反复荷载 破坏形态 延性 |

| Abstract: | From the experimental results of the two concrete filled steel tubular column(CFST),which reinforced concrete(RC) ring beam interior joints(JN-1 and JN-2) under static loads and quasi-static cyclic lateral loads,two aspects of ring beam joints on loading capacity and deformation capacity were analysed,the other aspects of ring beam joints on destroyed form,ductility,and energy dissipation,etc were also investigated.The experimental research indicated that in static load tests,the plastic hinges of ring beam... |
