  • Abstract An energy dissipating device system for bridges is
    proposed in the prese-ntstudies.The system consists of linear
    fluid dampers and relatively rigid lin-king members with
    leverage. The effectiveness of this system in terms of reduc-
    tion of the relative displacement of the superstructure of
    bridges is proven a-nalytically first. Then the dynamic
    responses of bridges with/without base iso-lation, subjectedto
    strong ground motions, are computed numerically. It is fou-nd
    that not only the maximum relative displacement but also the
    maximum base s-hear can be reduced significantly when the device
    system has been used on the bridge. Therefore, it is suggested
    that this device system be applied in the d-esign of new bridges
    as well as in retrofitting of existing bridges with inade-quated
    aseismic strength.
