[摘要]基于巨型框架核心筒结构体系中加强层伸臂桁架与巨型框架柱连接节点受力的特殊性,提出一种伸臂桁架复式钢管高强混凝土柱的连接节点形式,运用ABAQUS软件并结合深圳某超高层结构设计,对该节点展开详细的数值模拟分析。研究揭示了该节点的受力机理,并证明其在传力上的可靠性,可为该类节点在超高层结构中的应用提供参考。

Abstract:A new kind of connection between outrigger truss and double steel tubular confined with high performance concrete column was put forward according to the particularity of the connection performance between strengthened story with outrigger truss and mega frame column in mega framecore wall structure system. ABAQUS was used to simulate the behavior of this kind of connection combined with a tall building in Shenzhen. The research reveals the working mechanism and the reliability of load transmission of those joints. The design reference for the application of this kind of connection in tall building was provided.

Keywords:outrigger truss double steel tubular confined with high performance concrete column connection joint finite element analysis
