摘　　要：为了研究经过预埋式外包钢板-增大截面加固后柱贯通型RCS节点的承载能力和受力机理,结合实际工程,通过有限元软件ABAQUS对钢箍板-增大截面加固体系进行模拟计算,分析了钢箍板-增大截面加固体系核心区在作为刚接节点与铰接节点两种工况的设计荷载作用下,各部分结构的应力分布、损伤情况和节点转角。计算结果表明,在两种设计工况的作用下,各部分结构均处于弹性阶段,距离屈服强度还有较大盈余,混凝土结构局部出现损伤。In order to study the load carrying capacity and force mechanism of column through-type beam-column steel hybrid node after pre-buried outsourced steel plate-enlarged section reinforcement,combined with the actual project,through the finite element software ABAQUS simulation of steel plateenlarged section reinforcement system,analyzed the core area of the pre-buried outsourced steel plateenlarged section system in the core area of the system as a rigid joint node and articulated node under the action of the two conditions of the design load,the stress distribution and damage and the node angle of the various parts of the structure.The stress distribution,damage and node angle of each part of the structure under the two design loads as stiffened node and articulated node were analyzed.Calculation results show that under the two design conditions,all parts of the structure are in the elastic stage,and there is a large surplus from the yield strength,and the concrete structure is locally damaged.
