Breaking Tests on Three Full Size Prestressed Concrete Bridge Beams

This paper describes laboratory tests carried out to destruction on three prestressed concrete bridge beams, two of which were composite, partially prestressed beams, containing tensioned and untensioned wires. Load deflection curves and strain measurements have proved the full co-operation of tensioned and untensioned wires up to failure, the resilience being similar to that of ordinary prestressed concrete beams without untensioned wires.
