• Abstract:
  A procedure, using the rate-of-creep method, is developed for predicting creep strains, camber, and prestress loss in pretensioned prestressed concrete highway bridge beams. The procedure uses shrinkage data and creep per psi data, both expressed as functions of time, developed from small concrete specimens. Non-loaded pretensioned prestressed lightweight concrete beams 5 x 8 in. in section, 8 ft. long, were used to test the procedure. Creep and prestress losses taken from the beams were compared with values predicted by using the procedure developed in the paper. The method was extended to accommodate precast prestressed beams with cast-in-place reinforced concrete slabs, and laboratory beams were tested to verify the procedures.
