dc.description.abstract本文目的在探討增效式阻尼裝置應用於增加樓房結構阻尼比，使其成為高阻尼比結構系統，進而大量提昇其耐震能力之效果，經由理論分析、數值計算、振動台實驗驗證與實際案例分析，瞭解各相關因素之影響，並發展出適合在樓房耐震設計及耐震補強應用之裝置系統。 研究內容包括： (1)以理論分析與數值計算之方式，探討增效式阻尼裝置提高樓房結構阻尼比之程度，與降低樓房地震反應、提昇樓房耐震能力之有效性。 (2)利用振動台實驗，探討理論分析與數值計算之準確性與其使用之限制條件。 (3)依據計算容易與結果安全之原則，建立安裝增效式阻尼裝置鋼筋混凝土樓房耐震分析、設計與補強之方法與流程。 (4)根據所提之設計方法與流程，以一實際案例探討其可行性與成效。 研究結果顯示： (1)安裝增效式阻尼裝置確實可大量提昇樓房結構之阻尼比，並大幅降低其受震後之反應，進而提昇結構物之耐震能力。 (2)應用本文所提方法調整各樓層阻尼係數後，可使用反應譜分析法分析安裝增效式阻尼裝置之樓房結構系統之地震反應，獲得保守的結果，供工程耐震設計或補強之應用。 (3)本文定義一擬速度SV估算方法，可據以計算地震作用下液流阻尼器之最大阻尼力，便於利用反應譜分析法分析加裝增效式阻尼裝置之樓房結構地震反應，其計算結果可供設計時使用。 (4)本文提出應用增效式阻尼裝置於鋼筋混凝土樓房之新建與耐震補強設計流程，並以一實例進行耐震補強設計計算，可供工程界參考應用。zh_TW
dc.description.abstractThe objective of the present study is to investigate the effectiveness of the efficiency-enhanced damping system (EDS) on the reduction of vibrations of a structure with these systems to earthquakes. Also, the extent of enhancement for the damping ratio of a civil structure with the EDS and the aseismic capability of the structure have been studied. In addition, factors related to the effectiveness of vibration reductions have been studied numerically and experimentally. It is expected that a damping system which is suitable for use on buildings can be developed. Topics of study are as follows: (1)To investigate theoretically and numerically the feasibility and the effectiveness of the EDS on the improvement of the aseismic capability of the buildings. (2)To verify the accuracy of results and the related limitations of the theoretical analysis and numerical simulation using the shaking table experiments. (3)To develop the methods of analysis and procedures for seismic design and retrofitting of buildings with the EDS, especially for the RC building. (4)To perform the aseismic retrofitting analysis and design of a real RC building damaged in earthquake for demonstration. The results of the present study are as follows: (1)The damping ratio of a building structure can be largely increased and the seismic responses of the building can be reduced by using the EDS. Along this line, the aseismic capability of the building can be improved extensively. (2)The seismic responses of a building with the EDS can be analyzed by using the response spectrum method to obtain the conservative results for design or retrofitting of buildings if the damping coefficients of the device systems have been adjusted following the rule proposed in the present study. (3)The pseudo relative velocity (SV ) used to estimate the maximum damping forces developed in the fluid dampers of the EDS during earthquakes has been proposed which can be obtained by using the method of response spectrum analysis. (4)The method of analysis and the design procedures for establishing and seismic retrofitting of the RC building with the EDS have been proposed. In addition, the seismic retrofitting of a real 15-story RC building has been analyzed and designed for illustration.en_US
