［摘要］钢管混凝土柱提供很好的轴向刚度和承载能力，支撑体系则可满足侧向刚度的要求，故有支撑的钢管混凝土柱框架结构体系是一种经济有效的抗震结构。近10年来，许多学者以有支撑的钢管混凝土柱框架节点为研究对象，对其受力性能等方面进行了广泛的研究。阐述了有支撑的钢管混凝土柱框架节点性能的研究现状，提出该类型节点设计的关键问题；讨论不同的节点形式对其性能的影响，以及分析了节点板穿透式连接方式的有支撑钢管混凝土柱框架节点的数值模拟和试验的相关研究成果。从理论与试验的角度对节点性能进行总结，提出目前研究中存在的问题，以促进有支撑的钢管混凝土框架结构得到更深入地研究。

Abstract:The concrete-filled steel tubular columns provide good axial stiffness and load-bearing capacity. The supporting system can meet the requirements of lateral stiffness. Therefore, the structural system of braced frame connections with concrete-filled steel tubular columns is a cost-effective seismic structure. In the past ten years, many scholars have taken the braced frame connections with concrete-filled steel tubular columns as the research object, and conducted extensive research on their mechanical properties. The research status of the braced frame connections with concrete-filled steel tubular columns was described, and the key issues in the design of this type of connections were proposed. The influences of different connection types on the performances were discussed, and the related research results of the numerical simulation and the experiment of the braced frame connections with concrete-filled steel tubular columns using the penetration type connection method were analyzed. From the theoretical and experimental point of view, the performances of the connections were summarized, and the existing problems in the current research were proposed to promote more in-depth research on the braced  frame structure with concrete\|filled steel tubular columns.

Keywords:composite structure; braced connection; concrete-filled steel tubular column; connection performance
