[摘要]在地震和大风环境下,加设液体黏滞阻尼器是高层和超高层建筑最有效的结构振动保护措施。深入分析了4国内外已经建成和将要建造的安置液体黏滞阻尼器的以抗风为主的超高层建筑,并对液体黏滞阻尼器的减振效果和安置方式做了评述。对我国首次使用液体黏滞阻尼器的北京银泰中心和首次使用套索支撑阻尼器的天津国际贸易中心的计算分析、抗风设计做了阶段性的经验总结,最后简单介绍了以抗风为主的液体黏滞阻尼器所需具备的特殊要求。

Abstract:It is the most effective protective measure to use fluid viscous damper (FVD) to protect highrise and super highrise buildings from structural vibrations under the earthquake or strong wind. The indepth analyses on four built or inbuilt windcontrolled super highrise buildings with fluid viscous dampers at home and abroad were conducted, and damping effect and resettlement mode of the dampers were introduced. Calculations, analyses and wind resistant design were summarized as a stagey of experience based on Beijing Yintai Center as Chinas first use of fluid viscous damper and Tianjin International Trade Center as first using the toggle\|brace\|damper(TBD) in set of dampers in China. Finally special requirements on windresistance fluid viscous dampers were simply introduced.

Keywords:fluid viscous damper; wind vibration control; comfort level; togglebracedamper; damper power
