隨著都會區的密集開發，現今大樓多傾向向上興建，以爭取更多的利用空間，而台灣位於環太平洋地震帶上，因此對抗地震以及強風勢必成為高樓所要面對的首要問題。相較於大家耳熟能詳的調諧質量阻尼器(TMD)，現今國內也越來越多建案採取更簡易、更經濟的阻尼裝置―調諧液態晃盪阻尼器(TLSD)。本文針對TLSD的行為進行初步了解及驗證。首先，根據文獻提出的設計經驗公式進行數值模擬，以預估TLSD之波高及側向力的行為，也提供後續振動台試驗規劃與比對依據。接著考量振動台尺寸限制，針對標的主結構設計縮尺的TLSD裝置，進行單向振動台試驗。本文透過數值模擬與振動台試驗，透過等加速度試驗及簡諧振波試驗，也對於擋板位置及數量、擋板實心比、靜水高、外力振幅等變數之影響，進行一系列的驗證。綜合實驗結果，說明文獻中所提出之TLSD設計經驗公式在單向振動台試驗下，可以恰當預估縮尺TLSD的反應及頻率，在變換各種變因時，也可以掌握其反應的趨勢。

With the intensive development of urban areas, modern buildings increasingly tend to be constructed upwards to maximize space utilization. Given that Taiwan situates in Circum-Pacific Seismic Belt, buildings must prioritize resistance to earthquakes and strong winds. In addition to the well-known Tuned Mass Damper (TMD), there has been a growing trend in Taiwan toward adopting a simpler and more cost-effective damping device—the Tuned Liquid Sloshing Damper (TLSD). This paper provides an initial understanding and validation of TLSD behavior. First, numerical simulations are conducted based on empirical design formulas from the literature to estimate the wave height and lateral force behavior of TLSDs, providing a basis for subsequent shaking table test planning and comparison. Considering the size limitations of the shaking table, a scaled TLSD device was designed for the target main structure, and unidirectional shaking table tests were conducted. Through numerical simulations and shaking table experiments—including constant acceleration tests and harmonic wave tests—a series of verifications were performed on variables such as the position and number of screens, screens’ solidity ratio, static water height, and external force amplitude. The experimental results indicate that the empirical design formulas for TLSDs proposed in the literature can well predict the response and frequency of scaled TLSDs in unidirectional shake table tests and effectively capture response trends under various conditions.
