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 ...
Another fabrication system produces hollow-core floor slabs in reinforced concrete (not prestressed). These are made on carousel production lines, directly to exact length, and as a stock product. However, the length is limited to about 7-8 meters. Especially in Belgium, this method is widely used in private housing.
Modern multi-story parking structures are built from precast/prestressed concrete systems. The floor systems are mostly built from pre-topped double tees. This system evolved from the earlier use of tee systems where the flanges of the T-beams were connected. The concrete is then poured at the top of the tees during the construction to create ...
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
The Spancrete Manufacturers Association is an alliance of corporations that own Spancrete machines and produce precast, prestressed concrete. The group was formed in 1960 to promote the use of precast, prestressed concrete products and building systems worldwide.
The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport.
