    Abstract: 本文主要目的乃在探討外部預力節塊橋樑受車輛動力載重之反應,並與靜力分析結
    The purpose of this paper is to investigate the dynamic response of the externally
    prestressed concrete bridge due to vehicle loads and compare the results with static analysis .
    The finite element library consists of flat-facet shell elements, link elements and tendon
    elements which are used to model the concrete section, the key joints and the external
    tendons of the segmental bridge, respectively. The dynamic loading is simulated by a
    HS20-44 truck moving along the bridge. This model is then used for a three-span bridge with
    external prestressing. The variations of the displacements and the prestressing forces due to
    different loadings are presented. The ductility and the ultimate strength of the bridge are also
    discu ssed.
