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

摘要

The work presents a new original experimental rig to investigate more deeply the aerodynamic behaviour of long span suspension bridges. Set-up and model are designed to grant an accurate study on main aeroelastic phenomena, relevant in bridge engineering. More in details, experimental set-up and a 1:60 scale sectional model of Messina bridge deck are presented. The complete rig, composed by dynamometric model, suspension set and experimental set-up, is designed in order to execute both forced and free motion tests, by changing the average position in terms angle of attack and yaw angle and to investigate on flutter derivatives and vortex induced vibrations.
