摘　　要：钢筋混凝土梁与钢管混凝土柱节点受力性能是影响钢管混凝土柱结构应用的最关键问题。针对某电信枢纽中心的工程实践提出了穿心暗牛腿 +环梁的新型节点构造形式 ,对其依据相似原理进行了静载及反复荷载下的节点模型试验研究。结果表明 ,该节点传力路线明确、合理 ,受力性能较好。根据试验结果改进后的新型节点已用于工程实践。The working performance of reinforced concrete beam and steel tube confined concrete joint is vital to popularize steel tube confined concrete in China.A new type of steel tube confined concrete joint,put forward to solve the difficulty applied in a high rise building,is tested and researched under monotonic and reverse load.The tested result shows that the new type joint is working well and reliable to capacity.
