• 顫振臨界風速

  With the span of long-span bridges is becoming longer, the stiffness and damping ratio of structures decrease clearly and then critical flutter velocity falls accordingly. So flutter has been the most important problem in the design of long-span bridges.
  隨著大跨橋梁脩建的日益長大化，其剛度和阻尼明顯減小，因此顫振臨界風速也大幅降低，顫振問題成爲大跨橋梁抗風設(shè)計的關(guān)鍵。
