针对外加强环式节点及隔板贯通式节点的受力特点进行了介绍,并系统分析了大量的研究结果,指出这种节点容易在环板处形成破坏,为此提出了结合翼缘削弱的环板贯通式节点则可实现强节点。%This paper introduced the stress characteristics of connections with exterior diaphragms and diaphragm-through style beam-column joints,and system analysis on a large number of research results,pointed out that these joints were easy damaged in ring flat-plate,so this paper proposed diaphragm-through style ring flat-plate joints combining with flange weakening could achieve strong joints.
