Abstract
This invention relates to a production of a structure by means of arch stones. The arch stones comprise series of mixed steel-concrete arch stones (V.sub.M), each comprising a metal frame of steel integral with an upper concrete slab, these series being separated by interposed concrete arch stones or sections, (V.sub.B), the assembly of the arch stones being reinforced longitudinally by prestress cables which penetrate the metal frames and are attached at their ends to the concrete arch stones. This invention may be applied to bridge floors and similar structures.
