摘　　要：梁柱节点是装配式混凝土框架结构中的关键部位。根据节点中是否配置预应力筋,可以分为非预应力装配式梁柱节点和预应力装配式梁柱节点。综述了这两种节点的构造形式、国内外研究现状及耗能特点。设置阻尼器和无粘结预应力筋的自复位耗能节点以其耗能能力强、减小残余变形的优点未来将会有更好的发展前景。最后总结了装配式混凝土框架梁柱节点的特点,并提出了今后研究中需要解决的一些问题。Beam column joint is the key part of precast concrete frame structure.According to whether prestressed reinforcement is configured in the joint,it can be divided into non prestressed fabricated beam column joint and prestressed fabricated beam column joint.This paper summarizes the structural forms,research status and energy consumption characteristics of the two joints at home and abroad.Self resetting energy dissipation joints with dampers and unbonded prestressed tendons will be better developed because of their stronger energy dissipation capacity and reducing residual deformation.This paper summarizes the characteristics of beam column joints in prefabricated concrete frames,and puts forward some problems to be solved in future research.
