Abstract: A modular bridge is formed from a plurality of bridge modules. In one embodiment, the bridge includes: a first longitudinal compression member that is, in use, at an upper part of the bridge cross-section; a second longitudinal compression member that is, in use, at a lower part of the bridge cross-section; a structural lateral element for forming a deck of the bridge or for supporting deck elements of the bridge; a shear element for carrying a shear load; and a tension member applying a compressive force to one of the longitudinal compression members such that when in use the other of the longitudinal compression members forms a main compression element for the bridge and the tension member forms a main tension element for the bridge. The bridge modules form segments of the length of the bridge and each bridge module is of a one-piece construction.

Abstract: A modular bridge is formed from a plurality of bridge modules (4), the bridge (2) having a longitudinal direction along the spanning direction and including: a first longitudinal compression member (11,13, 70) that is, in use, at an upper part of the bridge cross-section; a second longitudinal compression member (9, 72) that is, in use, at a lower part of the bridge cross-section; a structural lateral element (9) for forming a deck of the bridge or for supporting deck elements of the bridge; a shear element (14, 16) for carrying a shear load; and a tension member (6) applying a compressive force to one of the longitudinal compression members (1,13, 70); (9, 72) such that when in use the other of the longitudinal compression members (1,13, 70); (9, 72) forms a main compression element for the bridge (2) and the tension member (6) forms a main tension element for the bridge (2).
