［摘要］目前，安裝輔助阻尼系統(tǒng)被認(rèn)為是控制建筑風(fēng)振響應(yīng)的一種既具有成本效益、又被廣泛認(rèn)可的方法，現(xiàn)已有一系列技術(shù)上很成熟的主動及被動裝置可供高層建筑設(shè)計時選用。從資金和營運(yùn)支出的角度出發(fā)，調(diào)諧液體阻尼器（TLDs）裝置由于具有相對較高的效率優(yōu)勢而獲得越來越多的業(yè)主青睞。通過案例分析，展示了達(dá)到調(diào)諧液柱阻尼器裝置性能優(yōu)化所需經(jīng)歷的設(shè)計和驗證過程，并對工程原理進(jìn)行介紹。

Abstract:It is now widely recognised that installing auxiliary damping systems is a cost effective and well established means of achieving building motion control for wind excitation. While a host of technically mature active and passive devices are now available to designers of tall buildings. Tuned liquid dampers (TLDs) are enjoying an increasing popularity amongst building owners on the basis that they are comparatively efficient devices from both a capital and operational expenditure standpoint. Making use of a case study, the design and validation process required to achieve performance-optimised devices of tuned ciquid damper were demonstrated and engineering principles behind this process was outlined.
Keywords:wind tunnel testing； aerodynamics； tuned liquid column damper； computational fluid dynamics
