The Prestressed concrete is a concrete system into which internal stresses are deliberately induced without any form of external loads to improve its performance. The simplest and strongest form of anchor bolt is cast-in-place, with its embedded end consisting of a standard hexagonal head bolt and washer, 90-bend, or some sort of forged or welded flange (see also stud welding).The last are used in concrete-steel composite structures as shear connectors.
