Abstract

The dependence of the aerodynamic characteristics of typical multi-beam structures of bridge spans on the angle of attack, the incident flow turbulence, the number of beams, and the distance between them has been studied. For the model of three beams bridge span, the characteristic vortex structures were obtained, the thermo-anemometer probing of the near wake was performed, and the diagrams of the distribution of the averaged pressure were plotted.
