应用液体黏滞阻尼器的高层结构抗风工程设计方法与实例

Design methods and examples of wind resistant engineering for high-rise building with liquid viscous damper

国内外建筑工程领域已经广泛认可了液体黏滞阻尼器在高层和超高层建筑上起到的抗震和抗风的结构保护作用。在国外超高层结构中,液体黏滞阻尼器的应用比例远高于其他结构保护措施,相比而言,阻尼器产品更加成熟,可信度更高。本文阐述了抗风阻尼器的技术特点及最新应用阻尼器抗风的项目中需要注意的问题。同时介绍了部分抗风案例,所述案例均采用了国际领先、技术成熟、久经考验的高强、高内压阻尼器。在超高层结构发展应用过程中,国际领先的阻尼器公司也有很多发展,长时间抗风阻尼器可选择的三个类型有:抗震又抗风的阻尼器;无摩擦金属密封阻尼器;改进型高功率阻尼器。

In the field of building engineering at home and abroad,liquid viscous damper has been widely recognized for its anti-seismic and anti-wind structure protection in high-rise and super-high-rise buildings. The proportion of liquid viscous damper is much higher than that of other structural protective measures in foreign super-tall structures. The technical characteristics of wind damper and the problems that need to be paid attention to in the latest application of wind damper are described. At the same time,some cases of wind resistance are introduced,all of which use internationally advanced,mature,time-tested,high-strength and high-internal pressure dampers. The international leading damper companies have also made a lot of progress in the development and application of super high-rise structures. Three types of long time anti-wind dampers can be chosen: dampers that are both anti-seismic and anti-wind,frictionless hermetic damper,improved high power damper.
