摘　　要：介绍了目前装配式结构中的混凝土框架结构,剪力墙结构和钢框架结构的连接技术研究动态,基于目前装配式结构连接技术存在的问题,提出一种可修复承载-耗能钢节点连接形式,对该节点连接方式的构造形式,工作机理,创新点进行简要的阐述,对其滞回曲线进行了分析。该结构可以将节点损伤集中在连接区处的削弱钢板上,实现节点的塑性铰外移;通过削弱钢板的承载和钢质铰的摩擦转动提高节点的耗能能力;保证梁柱主体在地震过程中不被破坏,在震后通过更换削弱钢板实现节点修复。This paper introduces the research trends of the connection technology of concrete frame structure,shear wall structure and steel frame structure in the current prefabricated structure.Based on the problems existing in the connection technology of the current prefabricated structural join,this paper puts forward a repairable bearing energy dissipation steel joint connection form,briefly expounds the structure form,working mechanism and innovation of the joint connection mode,and analyzes its hysteretic curve.This structure can concentrate node damage on the weakened steel plate at the connection area,achieving plastic hinge displacement of the node;Improving the energy dissipation capacity of nodes by weakening the load-bearing capacity of steel plates and the frictional rotation of steel hinges;Ensure that the main body of the beam and column is not damaged during the earthquake,and achieve joint repair by replacing weakened steel plates after the earthquake.
