Pre and post stressed concrete structure - Short Note

Pre and post stressed concrete structure

Prestressed concrete is the type of concrete in which permanent internal stresses are deliberately introduced to counteract to the design degree of stresses caused in the member in sauce. In this concrete tension is produced in lower side of the beam which naturalizes the comparison occur due to design load of beam.

In the procedure if wires/bars are stretched before casting of concrete is called priestesses concrete whaeas in post stressed concrete wires/bars are stretches after the casting of concrete.

In the process wires/bars are pass through hole/pipe left or cast in concrete.The working stressed adopted for prestressed concrete is much higher than the commen remforced concrete, thus it permitting the use of smaller and lighter section for the same laced.
