Abstract     [Full Text]
    This paper aims to describe the aerodynamic vibrations of various structural elements ofrnbridges, which are particular issues at present. The aerodynamic countermeasures for those vibrations arernalso discussed considering the generation mechanisms of the aerodynamic instabilities. In this paper, anrnexample of vortex-induced oscillation of bridge deck and its lesson are discussed. Next, the wind-inducedrncable vibration and its aerodynamic countermeasures are reviewed. Then, the aerodynamic characteristicsrnon two edge girders and their feasibility for application to long span cable-stayed bridges are considered.rnFurthermore, the bridge decks for future long span bridges are proposed and their aerodynamic characteristicsrnare also discussed.
 
Key Words
    bridge aerodynamics; vortex-induced vibration; cable vibration; flutter; two-edge girders; super long span bridges.
