河北工业大学图书馆结构消能减震设计

Seismic energy dissipation design on structure of the library in Hebei University of Technology

河北工业大学图书馆采用带屈曲约束支撑及黏滞流体阻尼器的消能减震钢筋混凝土框架结构，平面超限严重，且受建筑平面布局限制，仅能布置少量的支撑用于改善结构的抗扭性能。为使结构的层间位移角满足规范要求，在不影响建筑使用的位置的情况下，灵活布置了一些黏滞流体阻尼器。计算结果表明，结构各项计算指标均能满足规范要求，大震下黏滞流体阻尼器及屈曲约束支撑的耗能效果明湿，有效保护了主体结构，提高了整体结构的抗震性能。

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 arcbiteetttre 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 strueture and develop seismic performance of the overall structure.
