Study on the influence of baffles on the aerodynamic coefficients of long-span flexible bridge section

In the study of wind resistance performance of Bridges, the study of aerodynamic coefficients directly affects the accuracy of wind resistance performance of bridges. In this paper, the aerodynamic coefficients of main girder section of single-tower single-side suspension curve suspension cable footpath bridge are studied by numerical simulation and wind tunnel test. In order to improve the wind resistance performance of the bridge, the aerodynamic performance of the bridge section was improved by optimizing the bridge section and adding baffles, and the aerodynamic coefficient was obtained by wind tunnel test.
