    Abstract
  • The three-component force coefficients of streamlined sections of Sutong Bridge with different Reynolds numbers were calculated by using numerical simulation. The Reynolds number effect of streamlined section for bridge model with chord/thickness ratio of 10∶1 was investigated by wind tunnel test, the influence of Reynolds number on drag coefficient, surface pressure coefficient, wind pressure spectrum and Strouhal number was analyzed, and the restraining action of surface roughness on Reynolds number effect was researched. It is pointed that drag coefficient decreases with the increase of Reynold number. The zero position of surface pressure coefficient is subject to the influence of Reynolds number. Strouhal number exists platform effect because of the influence of Reynolds number. Strouhal number measured by wind tunnel test with low Reynolds number decreases by 20% compared with the one of practical bridge. Reynolds number effect of streamlined section is considerable. Surface roughness can restrain Reynolds number effect.
