Mar 20, 2014  Pre stressed concrete 1. Prestressed concrete is a method for overcoming concrete's natural weakness in tension. In 1904, Freyssinet attempted to introduce permanent acting forces in conc. to resist elastic forces under loads and was named “Pre Stressing”. It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete.

Introduction to prestressed concrete - SlideShare

Dec 11, 2011  Pre-tensioning In Pre-tension, the tendons are tensioned against some abutments before the concrete is place. After the concrete hardened, the tension force is released. The tendon tries to shrink back to the initial length but the concrete resists it through the bond between them, thus, compression force is induced in concrete.

Jan 10, 2016  Introduction 1.1 Background The idea of prestressed concrete has been around since the latter decades of the 19th century, but its use was limited by the quality of the materials at the time. It took until the 1920s and ‘30s for its materials development to progress to a level where prestressed concrete could be used with confidence.

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.

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.

The prestressed concrete bridge girder shown in Fig. 6.9 spans 21.6 m and supports a superimposed dead load G of 6 kN/m and a live load Q of 20 kN/m (excluding self-weight). A 150-mm thick topping slab was cast over the top flange of the beams after full stressing. The bridge is upgraded for HLPV resulting in an increase in the unfactored live loads applied to the beam.
