摘要
采用试验的方法对中海广场钢管混凝土柱-钢梁节点的性能进行了研究,得出该种节点的破坏形式、主要力学性能指标以及加强环上的应力分布。试验结果表明该种节点形式的承载力高、延性好,节点区加强环受力均匀,满足＂强柱弱梁＂的设计原则。对试验节点进行了有限元分析,数值分析结果与试验数据吻合较好,可为推广该节点形式的工程应用提供可靠依据。
Abstract
In order to investigate the mechanical behavior,the stress distribution in stiffening rings and the failure mode of concrete-filled steel tubular column to steel beam joints used in Zhonghai Square,the experimental method was conducted.The experimental results indicate that these joints which are new-type anti-seismic connections at present have a superior bearing capacity and good ductility,especially,excellent stress distribution in stiffening rings,which agrees in the ＇strong column-weak beam＇ design principle and the results between finite element simulation and experiment take good agreement,which should be deserved to be generalized widely in the similar projects.
