摘　　要：为研究带加强型节点的装配式轻钢再生混凝土框架在不同混凝土强度、柱截面尺寸以及柱高度参数下的破坏特性、承载能力、耗能能力、刚性变化。运用Abaqus有限元分析软件建立了27种模型,得出相应模型应力云图以及耗能曲线,对加强型节点的装配式方钢管再生混凝土框架结构进行优化分析。In order to study the failure characteristics,bearing capacity,energy dissipation capacity and rigidity variation of prefabricated lightweight-steel recycled concrete frame with reinforced joints under different concrete strength,column section size,column height and other parameters. In this paper,the finite element analysis software Abaqus is used to establish 27 models,and the corresponding model stress cloud diagram and energy dissipation curve are obtained,so as to optimize and analyze the prefabricated square steel tubular recycled concrete frame structure with reinforced joints.
