摘要
在建立了设置被动减振装置的高层建筑风振控制效果结构等效阻尼比计算公式的基础上，依据《建筑结构荷载规范》和高层建筑结构设计规程提出了设置被动减振装置高层建筑风振控制基于规范的实用设计方法。应用本文方法对设置矩形ＴＬＤ的上海中环广场超高层建筑的计算结果表明：本文方法具有简单、直观，且可与常规的结构抗风设计结果进行直接比较的特点，是风振控制规范化的一种设计方法，完全可为广大结构工程师所接受。
The objective of this paper is to establish a practical design method based on the design code for controlling wind induced vibration of tall buildings with passive absorbers. In the paper, the calculation formulas for equivalent structural damping ratio of control effect of passive absorbers for fluctuating wind vibration responses of tall buildings are derived. From this, a practical design method for controlling wind induced vibration of tall buildings with passive absorbers is presented based on both the load code of building structures and the structural design code of tall buildings. The calculation results by the method for the Shanghai Central Plaza, wihich is a thirty nine story reinforced concrete building with rectangular TLD,indicate that (1)The control effects of passive absorbers can be easily quantified and programmed into some common structural analysis programs for the design of tall buildings. (2)The method can be codified and its calculation results can be directly compared to the results of current structural design of tall buildings.
