Camber and Deflection Behavior of Prestressed Concrete Beams
The results of an investigation of non-composite prestressed concrete members, prior to cracking, using normal weight and lightweight concrete manufactured with Hawaiian aggregates are presented. Main emphasis is placed on initial and time-dependent camber and deflection. Also, initial and time-dependent loss of prestress and axial shortening are investigated. A procedure to select ultimate creep coefficients is compared with results obtained from tests on concrete cylinders made with the same aggregates and with coefficients suggested in published literature. Calculated values using experimentally determined constants are in good agreement with measured behavior. (Author)
