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.

Prestressed Concrete Pipe - an overview ScienceDirect

Prestressed concrete pressure pipes are covered by BS EN 639 and BS EN 642. The nominal size range is from DN 200 to 4000 and is the design internal diameter. American Standards AWWA C301-92 and C304-92 also cover large diameters. Examples of such pipe are typically DN 4000 up to 20 bar and DN 3600 up to 26 bar for North Africa.

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

Rules for Average Prestress — Kline Engineering

2016-11-28  Prestressed concrete is commonly used in many building and civil structure projects for its improved concrete performance. Average prestress is defined as P/A, where P is the final effective prestress force after losses and A is the cross-sectional area of the member (or design strip for two-way slabs). It is important to maintain P/A within certain defined limits.
