This example presents experimental and numerical data for aerodynamic forces acting on bridge deck cross-sections. Such data are widely used as benchmark references for validating CFD simulations and for assessing aeroelastic behavior in wind engineering applications. Flow around bridge cross-sections represents a complex aerodynamic problem involving flow separation, shear layer interaction, and wake development. Depending on the geometry and angle of attack, both steady and unsteady aerodynamic effects can occur, including vortex shedding, galloping, and flutter.
