Abstract:	本文目的為探討利用增效式阻尼裝置對於鋼筋混凝土樓房結構進行耐震補強之效果與相關之分析設計方法。研究內容可分為三部份，第一部份為利用真實地震之加速度反應譜對加裝增效式阻尼裝置之鋼筋混凝土樓房進行分析，計算樓層最大相對位移，瞭解其與該地震歷時之最大層間速度間之關係，進而求出液流阻尼器在地震作用下之最大阻尼力與結構桿件之受力。第二部份為安裝增效式阻尼裝置於鋼筋混凝土樓房時，該裝置與樑及柱接合處須注意之要點。第三部份為建立應用增效式阻尼裝置於鋼筋混凝土樓房進行耐震補強之分析與設計流程，並以一20層樓房為例說明之。本研究之具體成果： (1) 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，有便於加裝增效式阻尼裝置之結構地震反應利用反應譜分析法分析，其計算結果可供設計時使用。 (2) 本文提出應用增效式阻尼裝置於鋼筋混凝土樓房之耐震補強分析與設計流程，可供工程界參考應用。 The objectives of the present study are to investigate the effectiveness of the seismic retrofitting of the RC buildings using the efficiency-enhanced damping device and to develop the corresponding method for analysis and design procedures. The contents of this study are (1) to understand the relationship between the maximum relative displacement of floors by response spectrum method and the maximum relative velocity of floors by time history analysis. Along this line such that the maximum damping forces of the fluid dampers can be estimated. (2) to understand the stress states of the connecting sections between the efficiency-enhanced damping device and the structural members. and (3) to develop the method of analysis and design procedures for seismic retrofitting of the RC buildings with the efficiency-enhanced damping device system. In addition, the seismic retrofitting of a 20-story RC building is analysis for demonstration. The contribution of the present study are (1) the pseudo velocity (SV) which can be used to estimate the maximum damping forces developed in the fluid dampers during earthquakes with the response spectrum analysis being defined and (2) the method of analysis and the design procedures for seismic retrofitting of the RC buildings with the efficiency-enhanced damping device being proposed.
