[摘要]结合重庆瑞安超高层TP2塔楼具体工程,选取典型H型钢梁与钢管混凝土柱连接节点,采用SAP2000软件进行弹性有限元分析,并采用LSDYNA软件进行节点非线性分析,验证各节点构造在往复荷载作用下的性能,从而确定大直径钢管混凝土柱与钢梁刚接节点内部最优的构造形式,提高钢管混凝土柱钢梁连接节点的经济性和施工的便利性。

Abstract:
Based on TP2 tower of the Chongqing Shui On Land high\|rise building, a typical steel H beam\|CFT column connection joint was selected as the study object. An elastic finite element analysis was done by SAP2000. LS\|DYNA program was used for inelastic analysis to validate the performance of the joints under cyclic loading. So that the optimum internal detailing of major\|diameter CFT column\|steel beam rigid joint was obtained to improve economy and convenience of construction.
