Types of Prestressing Systems and Anchorages in …

In prestressed concrete structures, prestress is introduced by stretching steel wire and anchoring them against concrete. Therefore, the prestressing systems should comprise essentially a method of stretching the steel and a method of anchoring it to the concrete. Different systems are adopted for pre-tensioning and post tensioning. Contents:Types of Prestressing Systems1. Pre-Tensioning

Prestressed concrete - LinkedIn SlideShare

PRESTRESSED CONCRETE Prestressed concrete, invented by Eugene Frevssinet in 1928 is a method for overcoming concrete’’s natural weakness in tension . It can be used to produce beams , floors or bridges with a longer span than is practical with ordinary reinforced concrete. It can be accomplished in three ways: pre- tensioned concrete, and bonded or unbonded.
