Loss of prestress due to elastic shortening

At the transfer of prestress, tensile stresses of tendons are transferred to concretc in the form of compressive stresses. Due to this compression, elastic shortening ,, of length takes place in concrete. As the length of concrete member gets reduced,; an equal length reduction or strain takes place in tendons. Consequently, stresses ' in tendons are lost by a magnitude corresponding to this strain. This loss of prestress is called as loss due to elastic shortening of concrete.
