Sažetak
The possibility of using the fully reinforced lightweight concrete systems in the bridge structures is considered in this paper. Fully reinforced lightweight concrete systems are composed of steel reinforcement skeleton with the main bearing capacity and lightweight concrete body as a secondary bearing material for a local and global stabilisation. In this paper, two examples are given ; example of the grill-shaped overpass over four spans and box girder bridge over three spans. Lightweight concrete deck slab is reinforced with a grill-shaped reinforcement made of welded R trusses in two perpendicular directions. Reinforcement of the lightweight main girders, cross girders and walls of the lightweight box girder is designed as, at least, one truss with X-shaped diagonals.
