| dc.description.abstract | 2005年國內最新耐震設計規範，除將工址地震加速度進行微分區外，並增加工程品管、既有建築物耐震評估與補強，以及隔震、消能設計等等規章。然對於既有建築物耐震評估方法，僅要求“應為公認之學理”。但目前對外加消能裝置，造成高阻尼比鋼筋混凝土建築結構之耐震詳細評估方法，除直接使用非線性歷時反應分析外，尚無文獻討論。
本研究探討如何應用容量震譜法，進行安裝金屬製消能裝置之鋼筋混凝土建築物耐震詳細評估。其目的在建立應用容量震譜法，進行安裝金屬製消能裝置鋼筋混凝土建築物，耐震詳細評估之計算流程，以及瞭解應注意事項。並依據性能設計法觀念，定義建築物耐震能力判定基準。文中以十層樓房為對象，使用商業程式SAP2000，進行耐震詳細評估計算，將推覆分析之結果與三組與中壢地區設計反應譜符合之模擬地震之非線性歷時反應分析結果比較。研究結果顯示，直接建立具有金屬製消能裝置之鋼筋混凝土建築物模型，進行非線性推覆分析，可獲較保守之位移評估值，但基底剪力值須放大約1.3倍，方與非線性歷時反應分析結果相近，故推覆分析所得中壢地區之建築物耐震能力評估值，須乘以0.8後，方為耐震能力評估結果。 | zh_TW |
| dc.description.abstract | The newest domestic seismic design code in 2005 provides the microzonation of earthquake accelerations, the guidelines for quality control of construction, the principle of seismic assessment and retrofit of buildings and the guidelines for seismic design of base isolation and energy dissipation. Nevertheless, the method of seismic assessment is not specified and just states that the public acknowledged principle of analysis is required in the code. Furthermore, except from using the nonlinear time history analysis, there is not any method of seismic assessment for a heavily damped RC building with added damping device appeared in literature.
The present study is to investigate the application of the capacity spectrum method for the seismic assessment of the heavily damped RC building with added metallic damper. The objectives of the present studies are to set up the procedures of seismic assessment for that type of building and to understand the related factors which will affect the results of assessment. In addition, the guidelines for the evaluation of the seismic capability of a RC building with added metallic dampers are proposed. In this study, using the commercial program SAP2000, a 10-story RC building with and without added metallic dampers, are pushed horizontally. Results are compared with that of the nonlinear time history analysis using three different sets of simulated earthquakes compatible with the designed spectra of Jung-Li area. It is found that, in comparing with the results of nonlinear time history analysis, the displacement responses of the models, using the nonlinear pushover method, are conservative. But the maximum base shear force value of the RC building is under-estimated and should be enlarged with a factor of 1.3. Therefore, it is suggested that the estimated seismic capability of a RC building with added metallic dampers in Jung-Li area, using the nonlinear pushover method, should be reduced with a factor of 0.8. | en_US |
