摘　　要：框架节点是框架结构中重要组成部分,也是框架结构抗震的薄弱环节。本文简要阐述了混凝土框架节点加固的重要意义,详细介绍了加大截面、粘钢、外包钢及粘贴FRP等方法加固框架节点抗震性能方面的研究进展,期望为钢筋混凝土框架节点的实际加固改造提供应用参考。The Framenode is an important part in frame structure, and it is the weak part in the aseismic design of frame structure. In this paper we present the application of strengthening frame nodes, and review the progress of the earthquake performace of the frame Nodes reinforced by enlarging section, bonding steel plate, wrapping steel plate, and bonding FRP. It is helpful to provide the reference for the frame Nodes reinforcement in situ in China.
