AERODYNAMIC CHARACTERISTICS OF TYPICAL BRIDGE SPAN WITH TRAPEZIFORM GIRDER

UDK: 624.046.3

Salenko S. D., Gosteev Y. A., Obukhovskiy A. D.

The article is devoted to the dependence of aerodynamic characteristics of typical bridge spans with trapeziform girder on the angle of attack, turbulence level of main flotation and, cross-section configuration. Specific vortex structures were obtained. Heat-loss anemometer probing of near wake was performed. Averaged pressure profiles along construction surface were drawn. The effects of aerodynamic interference of two single-type bridge spans were studied.
