Some aspects pertaining the modeling of the aerodynamic behavior of bridge deck sections are presented. The analyses have been conducted by Computational Fluid Dynamic (CFD) codes (ANSYS and ADINA), with Finite Element Method (FEM) and Large Eddy Simulation (LES) based approaches respectively. The calibration of turbulence mathematical models, the robustness of the overall computational model and the behaviorchanges due to deck geometry or presence of traffic, are investigated by sensitivity analyses.
