Prestressing Steel| Concrete Construction Magazine
Prestressed concrete is composed of high-strength concrete and high-strength steel. Because of the high strength of these two materials, the resulting structures use much less concrete and steel and are, therefore, more economical. Concrete is an economical material for carrying compressive stresses, but has a very low tensile strength. In a prestressed concrete …

Prestressed Concrete Bridge - an overview | ScienceDirect
The prestressed concrete bridge girder shown in Fig. 6.9 spans 21.6 m and supports a superimposed dead load G of 6 kN/m and a live load Q of 20 kN/m (excluding self-weight). A 150-mm thick topping slab was cast over the top flange of the beams after full stressing. The bridge is upgraded for HLPV resulting in an increase in the unfactored live loads applied to the beam.
