Abstract
Under special conditions of turbulent wind, suspension and cable-stayed bri dges could reach instability conditions. In various instances the bridge de ck, as like a bluff body, could exhibit single-degree torsional instability . In the present study the turbulent component of flow has been considered as a solution of a differential stochastic linear equation. The input proce ss is represented by a Gaussian zero-mean white noise. In this paper the an alytical solution of the dynamic response of the bridge has been determined . The solution has been obtained with a technique of closing on the order o f the moments.
