【摘要】 钢筋混凝土梁与钢管混凝土柱节点的受力性能是影响钢管混凝土结构应用的关键问题.针对某电信枢纽中心的工程实践提出了穿心牛腿+环梁的新型节点构造形式,依据相似原理进行了静载及反复荷载下节点模型试验研究.试验研究表明,该节点传力路线明确,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.更多还原

【Abstract】 The 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 is put forward to solve the difficulty in application of highrise buildings,and it is tested and researched under monotone and reverse load. The results show that the new type joint performs well and is reliable to capacity.更多还原
