• 中文摘要： 本研究提出一種使用於橋梁結構之消能系統，此系統包括線性液體阻尼器以及產生槓桿作用之剛性連稈。研究中首先以理論推導，證明此消能系統具有降低橋梁上部結構位移之優異效果，然後進行橋梁承受強烈地震反應之數值計算。研究結果顯示此種消能系統不但可大量降低隔震或未隔震橋梁之上部結構相對位移，且可大量降低橋墩基底剪力，故此種消能系統除可應用在新建橋梁上，並可供補強現存耐震能力不足橋梁之用。
• 英文摘要： An energy dissipating device system for bridges is proposed in the present study. The system consistsof linear fluid dampers and relatively rigid linking members with leverage. The effectiveness of this systemin terms of reduction of the relative displacement of the superstructure of bridges is proven analyticallyfirst. Then the dynamic responses of bridges with/without base isolation, subjected to strong groundmotions, are computed numerically. It is found that not only the maximum relative displacement but alsothe maximum base shear can be reduced significantly if the device system has been used on the bridge.Therefore, it is suggested that this device system be applied in the design of new bridges as well as inretrofitting of existing bridges with inadequate aseismic strength.
