Wind Tunnel Tests of the Aeroelastic Stability of the Heer-Agimont Bridge
To investigate in a wind tunnel, the aeroelastic stability of the suspension bridge erected at Heer-Agimont (Belgium), tests were carried out on a sectional model of the bridge at a scale of 1/50 and on a model of the full bridge at a scale of 1/100. In both cases, the dynamic characteristics (mass distribution, stiffness and degrees of freedom) of the bridge were simulated with the appropriate scaling rules. The experiments were made in the open test section of the 3 m diameter L-1 wind tunnel. The wind velocity was varied until critical conditions, corresponding to self sustained bridge oscillation, were reached. Wind velocity, frequency of oscillations, mode and amplitude of the oscillations were recorded and used to define the stability characteristics of the bridge. (Author)
