（第二炮兵工程設(shè)計(jì)研究院，北京 100011）[摘要] 基于ABAQUS對(duì)采用剪切型鋼板阻尼器加固的某鋼筋混凝土框架結(jié)構(gòu)與原結(jié)構(gòu)的抗震性能進(jìn)行了罕遇地震下的動(dòng)力彈塑性時(shí)程分析對(duì)比。分析結(jié)果表明，未加固的框架結(jié)構(gòu)最大層間位移角不滿(mǎn)足規(guī)范要求，可能產(chǎn)生倒塌，增設(shè)剪切型鋼板阻尼器后可以顯著減小層間位移角并滿(mǎn)足規(guī)范要求，并對(duì)基底剪力有一定削弱，提高了結(jié)構(gòu)的抗震性能。分析方法可供類(lèi)似工程參考。[關(guān)鍵詞] 剪切型鋼板阻尼器; 框架結(jié)構(gòu); 動(dòng)力彈塑性時(shí)程分析; 抗震加固中圖分類(lèi)號(hào)：TU375.4 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)S2-0697-04作者簡(jiǎn)介：蔡振，碩士，工程師，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
