Therefore, creep of steel could be reduced considerably by overstressing steel about 10 above its initial stress and then releasing it to the initial stress. Shrinkage strain causes the steel to lose its stretch, resulting in the loss of prestress. To calculate the loss due to elastic shortening, loss in the first cable is calculated and half of this value is taken as the average loss of all the cables. When a cable is stretched, this cable suffers no loss, but the cable stretched before suffers a loss due to prestress in the cable being stretched. If the wires are successively tensioned, there will be loss of prestress due to elastic deformation of concrete. This reduction in the prestressing force is called loss in prestress. Triumph discography rapidshareĬontraction of steel wire occurs due to several causes, affecting reduction in the prestress. Loss due to Friction Total Loss of Prestress in Prestressed Concrete.

The results of this method are compared with the results obtained using Wood Armer method and using the moment coefficients suggested in IS 456-2000. This method is illustrated by considering the design of rectangular slab subjected to uniformly distributed load.
