Abstract
A bridge deck (10) is supported by tensile supports (11 and 12) and stabilized to reduce the overall aerodynamic lift on the deck (10) by the addition of aerofoil stabilizers (19 and 20) pivotally secured about respective axes (21) generally longitudinal of the deck (10). The stabilizers (19 and 20) are driven by a mechanism (21 to 26) operable by angular movement between the deck (10) and the tensile supports (11 and 12) to articulate the stabilizers (19 and 20) to a position which will generate a force, in the presence of a cross wind, to reduce the overall aerodynamic lift on the deck (10).
