［摘要］为研究钢筋混凝土柱-钢梁组合结构边节点在地震作用下的损伤，建立钢筋混凝土柱-钢梁组合结构边节点地震损伤模型，设计了两个钢筋混凝土柱-钢梁组合结构边节点试件，并对试件进行了低周反复荷载试验研究。结合试验结果，就Park-Ang模型和欧进萍模型对钢筋混凝土柱-钢梁组合结构边节点地震损伤研究的适用性进行了分析，提出了一种适用于钢筋混凝土柱-钢梁组合结构边节点的地震损伤模型。研究表明，提出的地震损伤模型能够很好地评价钢筋混凝土柱-钢梁组合结构边节点从“基本完好”到“倒塌”的整个损伤过程。［关键词］钢筋混凝土柱-钢梁组合结构边节点; 抗震性能; 地震损伤模型中图分类号：TU398 文献标识码：A 文章编号：1002-848X(2016)06-0055-06
Study on seismic damage model of single-sided joint of the RC column-steel beam composite structureSong Huifeng1, Zhang Yibao2, Pan Zhihong1, Zhou Zhibin3(1 School of Civil Engineering and Architecture, Jiangsu University of Science and Technology, Zhenjiang 212003, China; 2 Zhejiang Zhongnan Construction Group, Hangzhou 310000, China; 3 Shanghai Yingxiang Architectural Design Co., Ltd., Shanghai 200235, China)Abstract:In order to study the seismic damage of single-sided joint of the reinforced concrete(RC) column-steel beam composite structure and establish the seismic damage model of single-sided joint of the RC column-steel beam composite structure, two single-sided joints of the composite structure were designed and low cyclic loading tests were carried out on the specimens to research. Based on the test results, the applicability of Park-Ang model and Ou Jinping model in the seismic damage study of single-sided joint of the RC column-steel beam composite structure was analyzed and a seismic damage model suitable for the single-sided joint of the RC column-steel beam composite structure was raised. The results indicate that the proposed seismic damage model can well evaluate the whole damage process from basically intact to collapse state for single-sided joint of the RC column-steel beam composite structure.Keywords:single-sided joint of the reinforced concrete column-steel beam composite structure; seismic performance; seismic damage model
