高层建筑调谐液柱阻尼器的设计

Design of tuned liquid column dampers for tall buildings

目前,安装辅助阻尼系统被认为是控制建筑风振响应的一种既具有成本效益、又被广泛认可的方法,现已有一系列技术上很成熟的主动及被动装置可供高层建筑设计时选用。从资金和营运支出的角度出发,调谐液体阻尼器(TLDs)装置由于具有相对较高的效率优势而获得越来越多的业主青睐。通过案例分析,展示了达到调谐液柱阻尼器装置性能优化所需经历的设计和验证过程,并对工程原理进行介绍。

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.
