Title: Effect of Elastic and Creep Recoveries of Concrete on Loss of Prestresss
Author(s): Amin Ghali, Adam M. Neville, and P. C. Jha
Publication: Journal Proceedings
Appears on pages(s): 802-810
Keywords: beams (structural); creep (materials); creep recovery; modulus of elasticity; prestress losses; prestessed concrete; rlaxation; research; shrinkage; steels
Abstract:An expression for the loss of prestress accounting for the elastic and creep recoveries induced by the relaxation of steel is developed. Experiments verifying this expression for beams with different tendon eccentricities, and stored at two relative humidities are described. The use of this expression leads to a more accurate estimate of the loss in prestress which aims at economy in design.
