A summary on the experimental and analytical study of panel-type VE dampers would be included in the study. Cyclic loading tests and shaking table tests of panel-type VE dampers were carried out at the National Center for Research on Earthquake Engineering (NCREE). Under the cyclic loading tests, the full scaled panel-type VE dampers were used to study the force-displacement hysteresis behavior. Shaking table rests had been carried out on a 2/5 scale three story steel frame with panel-type VE dampers. Ground motions records such as the EL Centro, Capitola, Kobe, Newhall, Chi-Chi and three artificial earthquake time histories were used as the input ground motions for the shaking table tests. It can be concluded that the panel-type VE dampers are effective in reducing seismic vibrations of structures. The effectiveness of VE dampers does depend on the environmental temperature, vibration frequency and shear strain. Base of the experimental and analytical studies show that the seismic performance of panel-type VE dampers was also depend on the bending stiffness of the connect beams. Results of this study may be used in practical application of seismic resistant design of structures with panel-type VE dampers. Results from this study suggest that the bending stiffness of the connect beams would be stiffened enough to ensure the well action of the panel-type VE dampers. Finally, this study provides a revised equation for determining the damping ratio of the panel-type VE dampers considering the rotation of the connect beam, and the analysis results would be a reference for application of structures with panel-type VE dampers.誌 謝 I 要 IIIBSTRACT V 錄 VII目錄 IX目錄 XVII一章 緒論 1.1 前言 1.2減震結構基本概述 2.2.1 金屬阻尼器 2.2.2 黏彈性阻尼器 2.2.3 液態黏彈性阻尼器 3.3黏彈性阻尼器歷史[2] 3二章 黏彈性阻尼力學行為 5.1 基本力學行為[6][7][8] 5.1.1 擾動頻率[10][11][12][13] 9.1.2 環境溫度影響 13.1.3 阻尼內部溫度 14.2加黏彈性阻尼器之結構分析 16.3模態應變能法 18三章 壁式黏彈性阻尼器試驗研究 22.1 前言 22.2 試驗裝置 22.3 試驗用阻尼器 25.4 反覆循環載重試驗 28.5 阻尼器參數分析 38四章 振動台試驗 48.1 前言 48.2 試驗結構[18] 49.3 試驗流程 50.4 振動台試驗結果 59.4.1 位移與加速度歷時反應[19][20] 59.4.2樓層相對位移與層間位移角 60.4.3一樓純柱剪力 60.4.4底層阻尼器遲滯迴圈 60.5 振動台輸入歷時 62五章 加壁式黏彈性阻尼器結構分析模型 98.1 前言[21] 98.2 2/5比例三層兩跨鋼結構SAP模型 99.2.1原始構架模型 99.2.2加壁式黏彈性阻尼器結構模型 100.3 振動台試驗結果與SAP分析結果比較 102.4 振動台試驗模型分析探討 103六章 結論與展望 120.1 研究結論 120.2未來展望 121考文獻 1239840438 bytesapplication/pdfen-US被動消能控制器反覆載重循環試驗振動台試驗加速度反應譜位移反應譜阻尼係數法。the seismic performances of structurecyclic loading testsshaking table testsenvironmental temperaturevibration frequency and shear strain .thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/187718/1/ntu-98-R96521222-1.pdf
