摘要

摘要
改良式調諧液注阻尼器(improvement tuned liquid column damper, ITLCD)是以調諧液注阻尼器(tuned liquid column damper, TLCD)為基礎再以結合調諧質量阻尼器(tuned mass damper, TMD)而成；其具有調諧液注阻尼器(TLCD)之成本低廉以及兼具減振與可提供民生和消防用水之功能，更加上了調諧質量阻尼器(TMD)之優異的減振效果和安裝容易之優點。
本研究以接續前人之研究而發展至多自由度的探討(以三自由度為例)。首先先建立系統之數學模型與運動方程式，並決定出改良式調諧液注阻尼器(ITLCD)之參數，再以遺傳演算法(genetic algorithms, GA)去搜尋在不同的質量比下各組參數之最佳化，而進行結構物受被動控制前後之效能比較；而後再以被動之最佳化參數下，加入模糊滑動模式控制理論進行結構主動控制分析，最後，針對系統之主動與被動控制效能做評估與相互比較。
本研究以探討結構物裝設ITLCD之動態特性，以及量化系統被動與主動控制下之效能；而且以GA所搜尋出在不同的質量比下各組ITLCD之最佳化參數，可提供不同結構設計需求之參考。

Improved tuned liquid column damper(ITLCD)is combined with tuned liquid column damper (TLCD) and tuned mass damper(TMD).Improvement tuned liquid column damper have plentiful benefits, which has reasonable prices, helpful to reduce the quake and supply water for daily use and fire fighting. Furthermore, the TMD machine hade batter effect to reduce the quake and easier to install.
This research is extended an old theory and developed to degree of freedom (like three degree of freedoms). First, setting up the math model and action equation of the systems to defined the parameters of ITLCD.
Second , the reasurch is developed to search the best parameters in different quality by genetic algorithms (GA). Above-mentioned method will be compared with the passive control of efficacy from beginning to end upon the construction.
Third, according to the optimization of parameters, the research adds the Fuzzy Sliding Mode Control theory to analyze the active control onto structure. At last, the research estimates and compares the system of efficacy on active and passive control.
The main point of theory is to confer the ITLCD of active characteristic which is installed on the construction, And to discuss the quantification of system in active and passive control. Moreover , GA is assisted in findout the the ITLCD of optimization of parameter form different group of quality ratio, which can provide the data for numerous design of construction.
