調諧質量阻尼器（Tuned Mass Damper簡稱TMD）是一種在世界各大樓中廣泛被應用之減震裝置，其減震原理是將阻尼器之振動頻率設計成與主結構系統之第一振頻相近，當主結構受外力擺動時，TMD會因共振原理隨結構擺盪，而TMD在擺盪過程中與結構間的互制作用會減小結構之振幅。在結構控制中，以TMD作為控制元件之相關研究與實際應用，一直以來都是以控制因風力引起之振動或是中小規模地震力為設計考量，對於TMD之防震減震功能則較少討論。
TMD僅隨主結構之第一振頻擺盪，在外力造成遠離第一振頻之振動時，TMD之減震功能會因離頻效應而有所折減。本論文嘗試分析以液流阻尼器（Fluid Damper）對含TMD結構進行補強之功能。
由數值模擬結果可知TMD固然能降低主結構之反應，而經由液流阻尼器之補強後，即使地震力造成之振動頻率遠離第一振頻時，亦能進一步提升結構之位移與加速度反應，達到減震效果。

TMD only swung follows the first mode vibration of structure. If seismic force is far away from the first mode vibration of structure,it would reduce the effects upon TMD because of detuning effect.But someone would worry that it is not enough of energy dissipation.The Fluid Damper is chosen to reinforce the structural seismic resistance ability of the TMD system in this thesis.In accordance with the simulation results,it can be shown that TMD can effectively reduce the response of the structure.With the reinforcement of the Fluid Damper even if seismic force is far away from the first mode vibration of structure,it can also provide further reducing effects both in displacement and acceleration response.
