Prestressed Concrete Bridges

A concrete beam is “prestressed’ because stress is created before, or “pre,” the actual use of the beam when the working stress is applied. A properly engineered prestressed-concrete beam can span longer distances than a reinforced-concrete beam and it is thinner, lighter in weight, and uses less concrete

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.
