Abstract (EN): This paper describes a monitoring system installed at the Grande Ravine viaduct, in Reunion Island, and presents results of the analysis of the data recorded during a 2-year period. These include a characterisation of the wind based on the identification of predominant wind directions, incidence and mean velocity, as well as on local wind turbulence intensities, length scales and coherence. Additionally, force coefficients are assessed based on pressure full scale measurements, and compared with values established for design based on detailed wind tunnel studies. Finally, correlation between wind, pressures and the bridge response are established on the basis of the dominant wind directions.
