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.

Prestressed Concrete in Building: Advantages and Economics

Prestressed concrete is a method for overcoming concrete's natural weakness in tension. Prestressing tendons (generally of high tensile steel cable or rods) are used which produces a compressive stress that offsets the tensile stress that the concrete compression member would otherwise experience due to self–weight and gravity loads.

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.
