Despite the proven effectiveness of tuned liquid dampers (TLDs), readily available liquid storage tanks are rarely utilized for vibration control of laterally-excited structures, as these are deep tanks with low inherent damping. Further, the fluctuation in liquid level in these tanks also causes variation in the fundamental sloshing frequency, leading to detuning. To overcome these problems, a novel TLD with floating base (TLD-FB) is proposed, in which a constant and shallow liquid level is maintained between the free liquid surface and the floating base. The liquid above the floating base acts as a conventional shallow TLD that always remains tuned to the structural frequency. The paper demonstrates how the TLD-FB can be incorporated into a water storage tank system on an example building without disturbing its functionality and achieves structural response reduction, despite water level fluctuations in the tanks.

开发一种新型的带有浮动底座的调谐液体阻尼器，用于将深罐转换为有效的振动控制装置

尽管调谐液体阻尼器 (TLD) 的有效性已得到证实，但现成的液体储罐很少用于横向激励结构的振动控制，因为这些储罐是固有阻尼较低的深储罐。此外，这些罐中液位的波动也会引起基本晃荡频率的变化，从而导致失谐。为了克服这些问题，提出了一种新型的带浮动基底的 TLD (TLD-FB)，其中在自由液面和浮动基底之间保持恒定的浅液位。浮动底座上方的液体充当传统的浅层 TLD，始终保持调谐到结构频率。
