［摘要］河北工業(yè)大學(xué)圖書館采用帶屈曲約束支撐及黏滯流體阻尼器的消能減震鋼筋混凝土框架結(jié)構(gòu)，平面超限嚴(yán)重，且受建筑平面布局限制，僅能布置少量的支撐用于改善結(jié)構(gòu)的抗扭性能。為使結(jié)構(gòu)的層間位移角滿足規(guī)范要求，在不影響建筑使用的位置的情況下，靈活布置了一些黏滯流體阻尼器。計算結(jié)果表明，結(jié)構(gòu)各項(xiàng)計算指標(biāo)均能滿足規(guī)范要求，大震下黏滯流體阻尼器及屈曲約束支撐的耗能效果明顯，有效保護(hù)了主體結(jié)構(gòu)，提高了整體結(jié)構(gòu)的抗震性能。［關(guān)鍵詞］河北工業(yè)大學(xué)圖書館; 高層建筑; 消能減震; 屈曲約束支撐; 黏滯流體阻尼器; 性能化設(shè)計; 彈塑性時程分析中圖分類號：TU973.31 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2016)11-0044-05
Seismic energy dissipation design on structure of the library in Hebei University of TechnologyMeng Chunguang, Lu Xiuli, Liu Jianfeng, Geng Yaoming, Xi Zhenyong(Tongji Architectural Design (Group) Co., Ltd., Shanghai 200092, China)Abstract: The library of Hebei University of Technology adopts an energy-dissipated reinforced concrete frame structure with buckling restrained braces (BRBs) and viscous fluid dampers. There are serious irregularities in plane exceeding limitations of codes, and only a few braces can be arranged to improve the torsional rigidity of the structure considering the limit of architecture plane layout. In order to make interlayer displacement angle meet the specification requirements, some viscous fluid dampers were arranged at the location where they had no influence on the function of the building. The calculated results indicate that all calculation indices meet the requirements of current specifications and the energy dissipation effects of BRBs and viscous fluid dampers are obvious under the rare earthquake, which can effectively protect the main structure and develop seismic performance of the overall structure.Keywords: library in Hebei University of Technology; high-rise building; seismic energy dissipation; buckling restrained brace; viscous fluid damper; performance-based seismic design; elastic-plastic time-history analysis
