Abstract

Computer aerodynamic analysis of the bridge “Kazimierz-Ludwinów” located in Cracow, designed for pedestrians and bicycles traffic is presented in the paper. Authors’ own model of the dynamic wind action based on the quasi-steady theory has been applied. The data, obtained in model studies performed in a wind tunnel, have been assumed as the basis for calculation. The following aerodynamic coefficients have been measured: aerodynamic drag Cx, aerodynamic lift Cy, and aerodynamic moment Cw for three sections of the bridge as the functions of the wind attack angle in the range from -10° to +10°. The aerodynamic analysis presented in the paper includes: wind tunnel tests, determination of dynamic characteristics and calculation of the response of the bridge subjected to the dynamic wind action.
