| Abstract [Full Text] | |
| Under special conditions of turbulent wind, suspension and cable-stayed bridges could reachrninstability conditions. In various instances the bridge deck, as like a bluff body, could exhibit single-degreerntorsional instability. In the present study the turbulent component of flow has been considered as arnsolution of a differential stochastic linear equation. The input process is represented by a Gaussian zero-meanrnwhite noise. In this paper the analytical solution of the dynamic response of the bridge has beenrndetermined. The solution has been obtained with a technique of closing on the order of the moments. | |
