Bridge Design - PCI

Bridge Design. Precast is utilized to construct both the superstructure and substructures of all types of bridges. Superstructures include: flat slabs, adjacent box beams, pretensioned beams, spliced and curved girders. Whereas substructures include: precast end bents, piles and pile bent caps, water line pile caps, and precast columns.

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.
