Rapid Accurate Evaluation of Prestress Losses
ACI Journal Proceedings, 1973The difficulty in estimating accurately the losses due to creep, shrinkage, and relaxation of steel lies in: (a) prediction of coefficients related to the quality of concrete, steel, and environment in which the structure will be kept during the period of loss, (b) the interdependence of the amount of prestress loss produced by the three contributory ...

Prestress Loss as Affected by Type of Curing
PCI Journal, 1964This report describes a three-year investigation of the effect of accelerated curing conditions on the creep and shrinkage properties of the type of concrete frequently used in precasting plants. These concretes were proportioned to achieve a nominal compressive strength of at least 4,000 psi after five or six days of moist curing or in one day of ...
