（第二炮兵工程设计研究院，北京 100011）[摘要] 基于ABAQUS对采用剪切型钢板阻尼器加固的某钢筋混凝土框架结构与原结构的抗震性能进行了罕遇地震下的动力弹塑性时程分析对比。分析结果表明，未加固的框架结构最大层间位移角不满足规范要求，可能产生倒塌，增设剪切型钢板阻尼器后可以显著减小层间位移角并满足规范要求，并对基底剪力有一定削弱，提高了结构的抗震性能。分析方法可供类似工程参考。[关键词] 剪切型钢板阻尼器; 框架结构; 动力弹塑性时程分析; 抗震加固中图分类号：TU375.4 文献标识码：A 文章编号：1002-848X(2013)S2-0697-04作者简介：蔡振，硕士，工程师，Email：caizhen1000@163.com。The application of shear panel dampers in the retrofit of a concrete frame structureCai Zhen, Zhang Yongli, Yu Yue, Tian Xianbin, Han Lei(The Second Artillery Institute of Architectural Design and Research, Beijing 100011, China)Abstract: Comparative study was carried out on the seismic performance of a reinforced concrete structure retrofitted by shear panel dampers and original unstrengthened structure by means of elastic-plastic time history analysis using ABAQUS. The analysis results show that the unstrengthened structure may collapse because the maximal story drift angle is not satisfy the code requirement. For the structure retrofitted by shear panel dampers, the story drift angle is reduced significantly to meet the code standard, and the base shear force is mitigated effectively. Furthermore, the seismic performance is improved. The proposed method may help engineer in the similar project.Keywords: shear panel damper; frame structure; elastic-plastic time history analysis; seismic retrofit
