AEROSTATIC INSTABILITY ANALYSIS OF LONG SPAN BRIDGES INCLUDING BUFFETING EFFECT

    摘要
  • 摘要: 提出大跨度桥梁静风稳定性求解的动力有限元方法,在考虑桥梁结构几何非线性与脉动风抖振响应影响的基础上对西堠门大桥与东海大桥的静风稳定性进行了分析,计算结果表明,忽略脉动风抖振影响求出的静风失稳临界风速是偏于保守的.

     

    Abstract: Put forward a method which assesses the aerostatic instability of long span bridges by the approach of dynamic finite element analysis.The aerostatic instability of XIHOUMEN suspension bridge and east coast sea cable-stayed bridge which include the effects of geometric nonlinearity and buffeting are investigated.The analytical data shows that neglecting buffeting influence lead to conservative result.
