    Abstract: 本文探討橋梁結構合併使用摩擦單擺支承、加勁阻尼器與線性液體阻尼器之隔減震系統,對提昇橋梁耐震能力之效果,考慮不同特性之地震輸入,包括EL Centro、Mexico、Kobe與JIJI地震,研究結果顯示,三項隔減震裝置配合使用確實能有效減少橋梁上部結構相對位移反應,同時能減少橋墩所受的剪力,但在配合使用消能裝置時,橋台所受剪力則會增加,應值得注意。 In the present study, the effectiveness of the compound system, consisting of friction pendulum bearing(FPS), added damping and stiffness device(ADAS) and linear fluid damper(LFD) for bridges in terms of reductions of earthquake responses have been investigated numerically. The dynamic responses of bridges with / without this systems, subject to various strong ground motions, are computed numerically. The EL Centro earthquake, Mexico earthquake, Kobe earthquake and JIJI earthquakes are used as excitations. It is found that the combining use of these devices can largely reduce the relative displacement of the superstructure and the base shear of the pier. But the increasing burden of abutment after installation of the energy dissipation device system should be examined with care. Keywords:
