本文在建立了五种被动的动力减振器 (TMD， TLCD， LCVA， C TLD， R TLD)对高层建筑结构脉动风振反应控制的统一方程的基础上，导出了被动动力减振器对高层建筑脉动风振反应控制效果的等效结构阻尼比的统一计算公式和被动动力减振器优化参数的设计方法。在此基础上，文中依据我国《建筑结构荷载规范》，对设置被动动力减振器的高层建筑提出了抗风设计的荷载风振系数和脉动增大系数的修正公式，从而使被动动力减振器对高层建筑脉动风振反应控制的设计计算可采用常规的规范方法进行，大大方便了广大结构工程师的应用。

Practical Design Method for Effect of Five Kinds of Passive Dynamic Absorbers on Fluctuation Wind-induced Vibration Response Control of Tall Buildings

Based on the establishment of the unified formulas for control of fluctuation wind induced vibration response of tall buildings with five kinds of passive dynamic absorbers (TMD, TLCD, LCVA, C TLD, R TLD), the unified computing formulas of equivalent structural damping ratio for the controlling effect of passive dynamic absorbers on fluctuation wind induced vibration response of tall building and the design method of optimum parameters for passive dynamic absorbers have been derived. On this basis, the revised formulas for calculating wind load vibration coefficient and fluctuation magnifying coefficient in wind resistant design of tall buildings equipped with passive dynamic absorbers according to the Loading Code for Building Structure have also been put forward. Thus it is convenient for engineers to design the control of fluctuation wind induced vibration response of tall buildings equipped with passive dynamic absorbers using the conventional method given in the Code.
