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.

For instance, he was the first person to use prestressed continuous beams – in his design for Sclayn Bridge near Andenne; and it was Magnel’s Walnut Lane Memorial Bridge that inaugurated the use of prestressed concrete in the USA. Magnel’s monograph on prestressed concrete was therefore unique because it provided a comprehensive ...
A device that tensions prestressed concrete tendons. [1]: 36 [3]: 35–36 stressing stool A device interposed between the stressing jack and the concrete member during tensioning operations, to allow manipulation of the anchor block and seating wedges. Often used during lift-off testing. swage
Naturally precompressed exterior wall of Colosseum, Rome Cable-stayed prestressed concrete bridge over Yangtze river. In structural engineering, a prestressed structure is a load-bearing structure whose overall integrity, stability and security depend, primarily, on prestressing: the intentional creation of permanent stresses in the structure for the purpose of improving its performance under ...
Logo of Eurocode 2 An example of a concrete structure. In the Eurocode series of European standards (EN) related to construction, Eurocode 2: Design of concrete structures (abbreviated EN 1992 or, informally, EC 2) specifies technical rules for the design of concrete, reinforced concrete and prestressed concrete structures, using the limit state design philosophy.
Prestressed concrete is defined as a concrete construction material which is placed under compression prior to it supporting any applied loads (ie it is "pre" stressed). [1] This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete volume, and is done to improve the performance of the ...
