［摘要］为了研究钢筋混凝土柱-钢梁混合结构边节点的损伤模型，对比了常用的修正的Park-Ang模型和基于刚度的非累积损伤指数模型，设计了钢筋混凝土柱-钢梁混合结构边节点组合件，通过低周反复荷载试验进行地震损伤研究。结合试验结果，对钢筋混凝土柱-钢梁混合结构边节点的损伤模型进行了对比分析。研究表明，以钢梁弯曲破坏为主的钢筋混凝土柱-钢梁混合结构边节点基于刚度的非累积损伤指数模型模拟结果与试验结果符合较好；当滞回耗能因子β取0.05时，修正的Park-Ang模型也能较好地评价节点试件的损伤情况。

Abstract: In order to study the damage model of single-sided joint of the RC column-steel beam hybrid structure, commonly-used modified Park-Ang model and stiffness-based non-cumulative damage index model were compared. The single-sided joint specimen of the RC column-steel beam hybrid structure was designed to carry out seismic damage study through low cyclic loading test. Damage models of single-sided joint of the RC column-steel beam, hybrid structure were compared based on the test results. The results indicate that stiffness-based non-cumulative damage index model are in good agreement with the experimental results for such single-sided joint of the RC column-steel beam, hybrid structure that is mainly suffered steel beam bending failure. When hysteretic energy factor β is 0.05, the modified Park-Ang model can evaluate the damage of joint specimen effectively.

Keywords: RC column-steel beam; hybrid joint; seismic performance; seismic damage analysis
