本研究進行安裝增效式阻尼裝置樓房結構水平雙向振動台試驗，並與Sap2000數值模型理論分析計算結果比較，其目的在(一)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(二)瞭解結構動態理論分析與試驗結果之差距，以期發展出適合應用於樓房結構之消能裝置系統，以及可靠之結構耐震分析方法，供工程界之參考及應用。
試驗模型為三層之鋼構樓房(平面4.5m*3m、總高9.3m、總重約38噸)，於弱軸方向裝設增效式阻尼裝置，可調整為十一種不同阻尼比之結構，震動台地震輸入調整PGA之美國EL. Centro地震記錄、台灣集集Chi-Chi地震紀錄與日本阪神Kobe地震記錄，共計進行48組試驗。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 | ABSTRACT
In the present study, the shaking table tests of a 3-story building model equipped with the efficiency-enhanced damping device system (EEDS) subjected to 2D horizontal excitations are carried out. In addition, the Sap2000 software is used to compute the dynamic responses and the value of damping ratios of the building models. The objectives are (a) to investigate the capability of vibration reduction of the EEDS when it is used on a building and (b) to examine the difference among the results of numerical computations and the experimental results of the dynamic responses of a building with the EEDS. It is expected that 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 equipped with the EEDS along the weak axis. Eleven sets of damping ratio are achieved by adjusting the leverage and the number of linear fluid dampers used of the EEDS. The EL. Centro, the Chi-Chi and the Kobe earthquakes are used as excitations. Totally 48 sets of tests are carried out. Based on the response data collected, it is found that the EEDS can improve the aseismatic 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 on a building in practice. | en_US |
