Design of Pre-Stressed Concrete T-Beams

precast bridge beams between 10 and 30 m long and precast pre-stressed piles have proved to be more economical than steel and reinforced concrete in the United States. According to Abeles7, precast pre-stressed concrete is economical for floors, roofs, and bridges of spans up to 30 m. and for cast in situ work, up to 100 m.

Prestressed concrete - Wikipedia

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.

Considerable care should be exercised when handling structural precast concrete elements. In many cases, there is no way to repair a damaged element short of re-fabrication. Prestressed beams should be kept in an upright position at all times, as the beam’s own dead weight counter acts the internal prestressing force to keep the beam stable.
