摘要

調諧液柱阻尼器(tuned liquid column damper, TLCD)之優點為成本低廉、安裝容易，以及兼具減振與提供民生和消防用水的功能；調諧質量阻尼器(tuned mass damper, TMD)的優點則為安裝容易且具有優異之減振效用，改良式調諧液柱阻尼器為結合前述兩種阻尼器之混合式減振裝置，兼具兩者之優點。
本研究針對裝設改良式TLCD之樓房結構進行研究。首先，建立此系統之數學模型與運動方程式、提出時間域與頻率域分析流程，並決定改良式TLCD之最佳化參數；接著，將模糊滑動模式控制理論融入此模型，進行結構主動控制分析；最後，針對阻尼器之主動與被動控制效能進行評估與比較。
結果顯示改良式TLCD之被動控制效能優於傳統式TLCD，且接近TMD，在阻尼器最佳化參數的條件下，其反應折減率超過50%；改良式TLCD之主動控制效能則較被動控制最多提昇7%。
本研究探討裝設改良式TLCD之樓房結構動力特性、並量化此系統被動控制與主動控制之效能，其結果可提供樓房結構擬訂振動控制策略之參考。

The objective of this study is to detailedly investigate the dynamic characteristics of improved tuned liquid column damper. A mathematical model of building with improved tuned liquid column damper is developed. The fuzzy sliding mode control strategy is presented to reduce structural response under seismic excitation. On the basis of a computational procedure, both time domain analysis and frequency domain analysis are conducted to assess the effectiveness of the proposed algorithm. The optimal parameters of improved tuned liquid column damper are also suggested in this study. The results indicate that improved tuned liquid column damper has significant advantages for vibration control. In addition, the control effectiveness can be increased through fuzzy sliding mode control strategy.
