Three experimental cases are conducted in order to compare the control effectiveness of each case. A set of SF system consists of a window-shaped plate and two viscos dampers. The vibration of the window-shaped plate can provide additional stiffness to the primary structure. The window-shaped plate can be installed additional mass to tune the vibration frequency. Thus, the stiffness provided by SF system can be altered. The installment of two viscos dampers can provide additional damping to the primary structure. The concept of this SF system is similar to the conventional tuned mass dampers. Both systems contain a dashpot system to absorb energy. Furthermore, the vibration of the window-shape plate can also regulate the atmosphere and make this SF system more eco-friendly. The primary structure is NEREE’s eight-floor shear frame building. Three cases are conducted on shaking table. The EL Centro, Kobe, and TUC129 excitations are used for shaking table test. Performance test of viscos dampers are conducted before shaking table test to identify damping coefficient. Use subspace identification method to identify the dynamic properties of SF systems and compare the results with each case. The primary structure motion can be substantially reduced by SF systems introduced in this research. However, some case’s control effectiveness is limited. Investigating the inferior case and the perfect case by analyzing transfer function of SF system can find difference between two cases and give a reasonable explanation. Further research is required for adjust the mechanism of the SF system to make the control effectiveness more effective.口試委員會審定書 # 誌謝 i 中文摘要 ii ABSTRACT iii 目錄 iv 表目錄 vii 圖目錄 viii 第一章 緒論 1 1.1 研究目的與動機 1 1.2 文獻回顧 2 1.3 研究架構與內容 2 第二章 理論與設計原理 4 2.1 窗型調和質量阻尼器運動方程式 4 2.1.1 運動方程式 4 2.2 最佳化阻尼及勁度參數 4 2.2.1 Hartog’s Method 之設計公式 4 2.3 窗型調和質量阻尼器架構 6 2.3.1 窗型調和質量阻尼器架構簡介 6 2.4 阻尼器力學性質識別 7 2.4.1 阻尼器力學性質 7 2.4.2 阻尼器性能測試過程 8 2.4.3 阻尼器性能測試結果 8 2.5 計算窗型調和質量阻尼器之等效勁度 9 2.5.1 窗型調和質量阻尼器等效勁度 9 2.6 子空間系統識別法之理論介紹 12 2.6.1 子空間系統識別法 12 2.6.2 子空間識別法核心理論 14 第三章 實驗規劃與模擬 17 3.1 振動台試驗 17 3.1.1 空構架試驗 17 3.2 ETABS有限元素分析軟體的模擬 18 3.3 加載窗型調和質量阻尼器試驗 19 3.3.1 試驗一配置 19 3.3.2 試驗二配置 20 3.3.3 試驗三配置 20 第四章 實驗結果 21 4.1 試驗一控制結果 21 4.2 試驗二的控制結果 21 4.3 試驗三的控制結果 22 4.4 以SI法識別結構動態特性 23 第五章 實驗檢討 24 5.1 從輸出之訊號做單點奇異譜分析(SSA) 24 5.2 控制效果不佳之檢討 25 5.3 探討參數最佳化 26 第六章 結論與展望 29 6.1 結論 29 6.2 展望 30 參考文獻 31 附錄 1459581774 bytesapplication/pdf論文公開時間:2019/08/12論文使用權限:同意無償授權skin facades窗型調和質量阻尼器窗型調和質量阻尼器在結構減震控制上之應用Earthquake Response Control of Building Using Skin Facadesthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/260742/1/ntu-103-R01521204-1.pdf
