[摘要]在地震和大風(fēng)環(huán)境下,加設(shè)液體黏滯阻尼器是高層和超高層建筑最有效的結(jié)構(gòu)振動(dòng)保護(hù)措施。深入分析了4個(gè)國(guó)內(nèi)外已經(jīng)建成和將要建造的安置液體黏滯阻尼器的以抗風(fēng)為主的超高層建筑,并對(duì)液體黏滯阻尼器的減振效果和安置方式做了評(píng)述。對(duì)我國(guó)首次使用液體黏滯阻尼器的北京銀泰中心和首次使用套索支撐阻尼器的天津國(guó)際貿(mào)易中心的計(jì)算分析、抗風(fēng)設(shè)計(jì)做了階段性的經(jīng)驗(yàn)總結(jié),最后簡(jiǎn)單介紹了以抗風(fēng)為主的液體黏滯阻尼器所需具備的特殊要求。

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
