User's guide for prestress loss estimation procedures, March 1983 (FHWA-PA-83-005)

Two general procedures for the estimation of losses in prestressed concrete structural members are presented. Both are based on a rational analysis of the member, using experimentally established material characteristic equations. Both the computerized general procedure and the simplified manual procedure enable direct estimation of prestress loss at any specified time within the projected service life of the member. Detailed instructions are presented and several example problems are included to illustrate various features of the new procedures.
