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。
In this paper, based on the unified equations governing the pulsating wind-induced vibration response of high-rise building with five passive dynamic absorbers (TMD, TLCD, LCVA, CTLD and RTLD), the passive dynamic vibration absorber The uniform formula of equivalent structural damping ratio and the design method of passive dynamic vibration damper optimization parameters for the control effect of pulsating wind-induced vibration response in tall buildings. On this basis, based on China’s “Building Structure Load Code”, this paper puts forward a wind-resistance design load wind-vibration coefficient and a pulsation increasing coefficient correction formula for the high-rise building with passive dynamic vibration absorber, so that the passive dynamic damping The design and calculation of pulsating wind-induced vibration response control of high-rise building can be carried out by the conventional normative method, which greatly facilitates the application of the majority of structural engineers.
