LOSS OF PRESTRESS DUE TO RELAXATION AFTER TRANSFER

Expressions for direct computation of relaxation losses after transfer in low relaxation and stress-relieved steels are presented. The expressions were derived by iterating the applicable pure relaxation formula with a time-related function defining the rate of plastic strains in concrete. The resulting expressions were reduced to a form comparable with those in recent codes.
