Abstract

This paper deals with the possibility of using fully reinforced lightweight concrete systems in the bridge structures. Fully reinforced lightweight concrete systems are composed of a steel reinforcement skeleton with the main bearing capacity and lightweight concrete body as a secondary bearing material for a local and global stabilisation. Two examples are given in this paper; the example of a grill-shaped overpass over four spans and a 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. The 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.
