Abstract
In this paper the effects of low-frequency wind speed fluctuations on the aeroelastic stability of long span bridges are analyzed and discussed. The spatial-temporal field of wind turbulence is described by means of orthogonal loading components representing the eigenfunctions of the cross power spectral density function (cpsdf) of the wind process. The stability condition, derived through stochastic averaging technique and moment stability method, are finally applied to a bridge designed for crossing the Messina Strait (Italy).
