Typically, wires or "tendons" are stretched and then blocked at the ends creating compressive stresses throughout the member's entire cross-section. the loss of prestress can generally be attributed to the cumulative effects from the following sources: elastic shortening (fpes) relaxation of prestressing steel (fpr) shrinkage of concrete (fpsr) creep of concrete (fpcr) anchorage set (seating or slip) caused by movement of strands due to chuck seating in wedge-type Prestressed concrete May. No loss due to elastic deformation if all the wires are simultaneously tensioned. In PSC, the internal stress has been introduced under controlled circumstances before loading, to improve the shrinkage resistance of concrete and avoid the tensile cracks.
