BRIDGE WITH APPARATUS FOR ITS STABILIZATION AND BRIDGE STABILIZATION METHOD

摘要

A bridge deck (10) is supported by tensile supports (11 and 12) and stabilised to reduce the overall aerodynamic lift on the deck (10) by the addition of aerofoil stabilisers (19 and 20) pivotly secured about respective axes (21) generally longitudial of the deck (10). The stabilisers (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 stabilisers (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).
