Forced motion and free motion aeroelastic tests on a new concept dynamometric section model of the Messina suspension bridge

The work presents anew original experimental rig to more deeply investigate the aerodynamic behaviour of long span suspensionbridges. Set-up and model are designed to grant an accurate study on main aeroelastic phenomena in bridge engineering. More in details, experimental set-up and a 1:60 scale sectional model of Messinabridge deck are presented. The complete rig—composed by dynamometricmodel, suspension set, experimental set-up and active turbulence generator—is designed in order to execute both forced and freemotiontests, allowing to change the average position in terms of angle of attack and yaw angle and to investigate flutter derivatives, admittance functions and vortex-induced vibrations.
