Prestressed concrete - Wikipedia

Prestressed concrete is a highly versatile construction material as a result of it being an almost ideal combination of its two main constituents: high-strength steel, pre-stretched to allow its full strength to be easily realised; and modern concrete, pre-compressed to minimise cracking under tensile forces. Its wide range of application is reflected in its incorporation into the major design codes covering most areas of structural and civil engineering, including buildings, bridges, dams, foundations, pavements, piles, stadi

Prestressed concrete Wikidwelling Fandom

Prestressed concrete is a method for overcoming concrete's natural weakness in tension.12 It can be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete. Prestressing tendons (generally of high tensile steel cable or rods) are used to provide a clamping load which produces a compressive stress that offsets the tensile stress that the ...

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.

Why Prestressed? - National Precast Concrete Association

The idea of prestressing concrete was first applied by Eugene Freyssinet, a French structural and civil engineer, in 1928 as a method for overcoming concrete’s natural weakness in tension. Prestressed concrete can now be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete.
