ABSTRACT:
The composite structure made of wood and reinforced concrete can be used for bridges, roofs etc. In a bridge, a plate of reinforced concrete carries the roadway and rests on a truss comprising lower and upper chords, transversal girders and struts made of wood and posts made of reinforced concrete. The lower struts are reinforced with steel ties, follow a bent curve and are anchored in lateral end sections. Forces in the wooden parts all extend along the wood's fibre, which increases the maximum load capacity. The concrete posts allow a simple assembly of the wooden elements. The weight of the construction is low, its load bearing capacity high.
