Abstract
Framework for a suspension bridge of the type comprising an essentially flat main structure, the top surface of which forms the traffic lane for the transport structure crossing the bridge, anchored to a suspension system formed of a plurality of vertical hangers (6) fixed to catenary cables (5) anchored to end piers of the bridge. The framework consists of at least two parallel longitudinal box-like bodies corresponding to two runways of the bridge, reciprocally spaced by an extent equal to their transverse dimension. Said bodies have a cross section with a profile adapted to favor the proper flow of the wind stream and they are interconnected, at regular intervals, by stiff supporting transverse ledgers (4) having in turn a box-like configuration and carrying at their ends means for their anchorage to the suspension hangers (6).
