NCDOT: Prestressed Concrete Channel Beam Bridges

Jul 15, 2020  The Sta te Bridge Maintenance Unit adopted two standard, prestressed concrete channel beam designs in 1956. The first was for channels of 20-, 25-, or 30-foot-long spans and 15-ton (H15) truck loads. This was a straightforward channel-beam bridge with the beams stiffened by transverse ties and the adjacent channels also serving as the deck.

Prestressed concrete beam - concast - rectangular

Description. Pre-stressed beams can span longer distance at similar depths than ordinary reinforced beams. They can also reduce the amount of steel required in a beam, and therefore can be produced at a lower cost. These beams can have similar cross sections to standard bridge beams, or can have a new cross section.
