結構加裝液流阻尼器後,利用結構動力推導運動方程式的方法,可推出樓房安裝阻尼器的運動方程式,並利用線性加速度法可解此運動方程式。本研究以國家地震中心三層樓鋼結構實尺模型安裝液流阻尼器為例,比較安裝各種不同n值之液流阻尼器的結構控制效果與最佳配置。分析結果顯示,外力很小時,n值較小的阻尼器可發揮較好的控制效果;但是外力較大時,n值小的阻尼器不一定比較佳。在最佳配置方面,本研究使用基因演算法搜尋阻尼器之最佳配置模式,分析結果顯示,一樓安裝n值最大的阻尼器,會有較好的控制效果。二樓與三樓的阻尼器搭配,可為最大n值阻尼器搭配n值為中間偏大的阻尼器,或者選擇以n值為1左右的阻尼器搭配n值最小的阻尼器,會有較佳控制效果。
When the structure is equipped with Fluid Dampers, the equation of motion can be done.The way making use of dynamic of structure to deduce the equation of motion could infer the equation in which damping force is installed in the building. Furthermore, the later equation shall be solved by the method so called the linear acceleration method. This thesis bases on an three-floor SRC building, of real size, equipped with Fluid Dampers, and exhibited in NCREE(National Center for Research on Earthquake Engineering). In addition, the thesis will offer the structural control efficiency for fluid dampers of various n value is installed in the building, and how the best equipment would be. The experiment proved that, with less external excitation the damper of less n value gives better control effect, while with greater excitation not necessarily so. However, what could be the best equipment? By using the Genetic Algorithms, there will be the better control results when the damper with the largest n value is installed at the first floor. As for the second and third floor, the best control results would be the assemblage of the largest and middle larger n value, or damper of the smallest n value assembled with the damper of n value is approximately equal to 1.
