The basic types of prestressing are: Precompression with mostly the structure's own weight Pre-tensioning with high-strength embedded tendons Post-tensioning with high-strength bonded or unbonded tendons Today, the concept of a prestressed structure is widely employed in the design of buildings, underground structures, TV towers, power stations, floating storage and offshore facilities, nuclear reactor vessels, and numerous bridge systems. It is especially prominent in construction using concrete (see pre-stressed concrete). The idea of precompression was apparently familiar to ancient Roman architects. The tall attic wall of the Colosseum works as a stabilizing device for the wall piers beneath it. == References == - [[Professional Practice/Codes & Standards/National Building Code of India/Part 06 - Structural Design/Section 5B - Prestressed Concrete]] - [[Building Construction/Structural Systems/Concrete Structures]] - [[Building Construction/Structural Systems/Masonry Structures]] - [[Building Construction/Structural Systems/Steel Structures]] - [[Building Construction/Structural Systems/Timber Structures]] - [[Structures/Structure Systems & Design]] - [[Wiki-Architecture/Buildings and Structures]] - [[Wiki-Architecture/Infrastructure]] - [[Structures]] - [[Structures/Structural Engineering]]
