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 without cracking or breaking.

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 - Wikipedia

Jul 17, 2004  Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during production, in a manner that strengthens it against tensile forces which will exist when in service.: 3–5 This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service.

Prestressed Concrete: Types, Advantages Disadvantages

Prestressed concrete components are similar to normal concrete but it has high strength concrete and high tensile steel wires. High-grade concrete is used in prestressed concrete because reinforcement imposes large pressure forces for members causing high stresses at the ends to be developed by anchoring equipment.

Precast Concrete Homes Florida Engineering

Benefits of Precast Concrete Homes. One huge benefit that precast concrete offers homebuilders is the ability of the material to serve as a weather-resistant factor. Weather extremes, such as excessive heat or cold, are well guarded against by the concrete structure, making the internal temperature much more easily controlled.
