AB  - Results of an experimental study related to flutter phenomenon are presented in the paper. Two cross-sections are considered: a rectangular cross-section and a typical symmetric bridge cross-section. Stationary coefficients and instationary flutter derivatives are determined by means of forced vibration tests. The identification technique is presented in detail. Pressure measurements at the centre of the bridge cross-section are also performed. Main wind flow patterns are analysed based on pressure distribution data.

AB  - The 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.
