摘　　要：目的为了研究钢骨高强混凝土柱/钢筋高强混凝土梁框架边节点的损伤发生、发展情况.方法利用损伤原理,根据试验情况,对钢骨高强混凝土柱/钢筋高强混凝土梁框架边节点的损伤进行研究。结果建立一种适合低周期反复荷载作用下的损伤模型,并进行了损伤与弦转角的关系分析,从而对其损伤机理、损伤过程及损伤的影响因素有更进一步的了解.结论建立了HSRC柱/HRC梁框架边节点在低周反复荷载作用下的损伤模型.结构的损伤经历3个阶段,在其他条件都相同而轴压比不同的情况下,轴压比越大其损伤值越大,其延性也越差;在其他条件都相同而核心区配箍率不同的情况下,核心区配箍率越小其损伤值越大,其延性也越差.In order to study the damage occurrence and development of the SHRC/HRS frame side joints, the damage theory and test have been used to study the damage to the SHRC/HRS frame side joints. The damage model has been made and the analysis of the relation damage and turn angle has been studied to give a better understanding of the damage theory, damage course and damage effect factors. The article draws the conclusion that the damage has three courses, which in other conditions are the same but the axial compressive ratios are not the same. If the axial compressive ratio is larger and the damage is larger, the ductility is worse. Those in other conditions are the same but the rates of stirrup used in core area are not the same. If the rate of stirrup used in core area is smaller and the damage is larger, the ductility is worse.
