dc.description.abstractThe widely used formulation of aeroelastic forces presented in the work of Scanlan and Tomko (1971) relies on the frequency dependent coefficients - flutter derivatives and wind tunnel experiments as their identification tool. The lack of analytical solution for flutter phenomena at bridges is related to the complexity of flow separations from a typical bridge deck. Numerical approaches can be considered for identification of aeroelastic forces. Nevertheless, it has to be kept in mind that numerical simulations are often jeopardized by the limitations related to poor detection of separation regions. In order to estimate the influence of these limitations over the computed flutter derivatives, this study employs 3D Large Eddy Simulation (LES) and 2D Unsteady Reynolds-Averaged Navier-Stokes (URANS) approaches.en
