| dc.description.abstract | 本研究進行安裝增效式阻尼裝置樓房結構之振動台試驗，其目的在(一)熟悉樓房振動台試驗及相關資料處理工作，(二)瞭解增效式阻尼裝置於降低樓房地震反應、增進樓房耐震能力的效果，與(三)瞭解結構動態理論分析與實驗結果之差距，以期發展出適合應用於樓房之隔震消能裝置系統以及可靠之結構耐震分析方法，供工程界之參考及應用。
實驗模型為五層樓之鋼構樓房(平面2m*2m、總高6.7m、總重約5.6噸)，於強軸方向裝設增效式阻尼裝置，可調整五種不同阻尼比進行震動台地震反應試驗，輸入調整之EL. Centro地震記錄與調整之日本阪神地震記錄，共計進行42組試驗，由試驗數據分析樓房受震行為與樓層反應降低情形。研究結果顯示，增效式阻尼裝置可大量提升樓房結構之耐震能力，為良好之減震裝置，且理論分析能充分掌握樓房之地震反應，可供工程界設計分析之用。 | zh_TW |
| dc.description.abstract | In the present study, a 5-story building model equipped with the efficiency-enhanced damping device system (EEDS) is tested on the shaking table. The dynamic responses of the model to earthquakes are also computed numerically. The objectives are (a) to make acquaintance with the process of the building model shaking table test and the related technique of data processing, (b) to investigate the capability of vibration reduction of a building with the EEDS and (c) to verify that the results of numerical computations can predict the dynamic responses of a building with the EEDS accurately. It is expected an effective vibration reduction system for buildings can be developed and a reliable method of numerical computation for a building with energy dissipation system can be obtained.
The building model is a 5-story steel structure equipped with the EEDS along the strong axis and with five different values of damping ratio achieved by adjusting the leverage of the EEDS. The EL Centro earthquake and Kobe earthquake are used as excitations. Totally 42 sets of tests are carried out. Based on the response data collected, it is found that the EEDS can raise the aseismic capability of a building to a great extent. In addition, the dynamic responses of a building equipped with the EEDS to earthquakes can be predicted by numerical analysis accurately. Therefore, the EEDS is one of the effective vibration reduction systems that can be used in practice. | en_US |
