THE WIND TUNNEL TEST OF THE AEROELASTIC MODEL OF A STADIUM

The long-span stadium is a wind-sensitive structure. Due to the difficulty in designing and manufacturing the aeroelastic model, there is still little wind tunnel test of such structure. In this paper, an aeroelastic model of a long-span stadium was manufactured and tested in wind tunnel. The effects of wind speed and wind direction on the displacement response were analyzed. In addition, wind pressure of the aeroelastic model were also measured to make a comparison with that of rigid model. The results showed that the maximum displacement of the roof structure occured at the position perpendicular to the wind direction. The displacement response increased with wind speed, the higher the wind speed, the higher the growth rate. It was also found that there was little difference in mean wind pressures between aeroelastic model and rigid model, while the fluctuating wind pressures of aeroelastic model were larger than that of rigid model.
