ABSTRACT:
A deployable bridge is assembled from individual components. The components include cross girders and pavement slabs disposed between the cross girders, the cross girders each having opposite ends and first and second continuous girders each disposed along one of the opposite ends, respectively, of the cross girders. Each continuous girder comprises an upwardly pointing truss having top and bottom chords and truss members arranged between the top and bottom chords and connected to the top and bottom chords at top and bottom nodal points, respectively. The top and bottom chords are each divided in regions of the top and bottom nodal points into a plurality of top chord members and bottom chord members. Each continuous girder further includes connecting elements connecting together the top chord members and connecting together the bottom chord members. The truss members are affixed at a top end to the connecting elements of the top chords and at a bottom end to either the connecting elements of the bottom chords or the ends of the cross girders.
