The Concrete-Filled Steel Tube (CFST) outer reinforced ring joints refer to the joint part of the CFST column and beam to form a whole through the use of outer reinforced ring plates, which is the key part to ensure the safety and durability of the structure. Firstly, in this paper, the research on the structural forms of Concrete-Filled Steel Tube (CFST) outer reinforced ring joints at home and abroad is analyzed. Welding is often used to strengthen the connection between ring plate and beam column. With the popularity of prefabricated structures, high-strength bolts are gradually applied to strengthen the connection between reinforced ring plate and beam. By further comparing the studies of seismic performance of concrete-filled steel tube joints at home and abroad, it is concluded that such joints show good working and seismic performance, and have a wide application prospect. Finally, the calculation formula of the shear-bearing capacity of this kind of node is summarized and analyzed. Relevant norms at home and abroad have provided mathematical calculation formulas, but with the constant change in the structural form of the joint and the processing material, the existing formulas may have some limitations. Academic research and engineering practice show that CFST outer reinforced ring plate has good rigidity, ductility and seismic performance. Therefore, by sorting out and summarizing the latest research results, the reliable experience is provided for the subsequent research on the new structures and properties of CFST outer reinforced ring joints. %K 钢管混凝土,外加强环式节点,构造形式,抗震性能,抗剪承载力
