Highway Overpass in Lightweight Reinforced Concrete

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.The overpass, designed in lightweight reinforced concrete, which is to cross the highway, is presented. Four spans 15, 0+19, 0+19, 0+15, 0m are chosen to provide the sufficient traffic profile of the highway and its eventual expansion. The overpass is a grill-structure composed of three main continuos girders at the distance of 3, 5m connected with the 25cm thick slab and 100cm high cross girders at the end and in the middle of each field. A span to height ratio of the structure is 19, 0/2, 0=9, 5. Lightweight concrete roadway slab is reinforced with a grill-shaped reinforcement made of welded R trusses in two perpendicular directions. Lower R trusses of longitudinal direction are pull into the higher R trusses of transversal direction and no particular connection is predicted. Reinforcement of the lightweight main girders and cross girders is designed as, at least, one truss with X-shaped diagonals.
