Abstract

The cable stayed bridge of Talavera de la Reina in central Spain is a signature structure of a high aesthetic quality, the main span is 318 m long and the single pylon reaches 164 m of height. Due to the relevance of the bridge a study of the wind characteristics at the location and a set of aerodynamic studies both experimental and computational were carried out to anticipate the future response of the bridge under wind flow. They comprised a boundary layer wind tunnel test of the stand alone pylon and the full bridge, a test of a reduced model of a segment of the deck in an aerodynamics wind tunnel and computational analysis to obtain the flutter speed of the bridge. This paper describes the bridge and the results of the mentioned studies that allowed us to conclude that the bridge could perform safely while subjected to the expected wind speed at its location. Keywords: cable stayed bridges, boundary layer wind tunnel, aeroelastic studies, flutter speed.
