Abstract:

The aeroelastic response of bluff bodies is strongly influenced by atmospheric turbulence contained in the wind. The accurate prediction of wind-induced dynamic response of line-like structures such as bridges and towers requires modelling of the cross sectional aerodynamic behaviour, the structural dynamics and the wind characteristics. This study aims to integrate all these aspects by performing CFD analyses in slices that are coupled to a three-dimensional structural model and performing fluid-structure interaction analyses that are able to account for turbulent inflow conditions. The method is applied to the study of a cable-stayed bridge and the results are verified against wind tunnel measurements.
