| Abstract: |
The paper examines aerodynamic characteristics of close and parallel automobile and rail bridge arches. Aeroelastic stability of the bridge arches is investigated in a specialized wind-tunnel. It is found that the automobile bridge span is subject to vortex-induced oscillations. These oscillations are reduced by arrangement of a fairing on the bridge-span stiffening girder. Possibility of a buffet- type aerodynamic instability is examined in detail. |
