Prestressed Concrete Erection

prestressed concrete Topic

Jul 01,  · Prestressed concrete is structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads. This introduction of internal stresses is called “prestressing” and is usually accomplished through the use of tendons that are tensioned or pulled tight prior to being anchored to the concrete.

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.
