Prestressed Post-Tensioned Concrete Section
Prestress is defined as a method of applying pre-compression to control the stresses resulting due to external loads
below the neutral axis of the beam tension developed due to external load which is more than the permissible limits of
the plain concrete. The pre-compression applied (may be axial or eccentric) will induce the compressive stress below
the neutral axis or as a whole ofthe beam c/s. Resulting either no tension or compression_Prestressed concrete is
basically concrete in which internal stresses of a suitable magnitude and distribution are introduced so that the
stresses resulting from the external loads are counteracted to a desired degrees
