Abstract This study deals with the dynamic behavior of long-span cable-stayed bridges under various wind effects. The novelty of this study is the consideration of an initial static equilibrium state subjected only to the self-weight of the bridge at various construction stages under complex buffeting winds. In particular, the dynamic response of a bridge prior to closure of the superstructure at the main and side spans are studied using a newly developed finite element program. The numerical results obtained for an existing three-span cable-stayed bridge model are compared to data from laboratory scaled-model testing. The parametric studies are focused on the various effects of wind speed on the dynamic behavior of cable-stayed bridges when the initial static equilibrium states at different construction stages are considered.
