Abstract

An analytical method for predicting shrinkage deformations in both cracked and uncracked states is discussed. The validity of this method was verified by conducting an experimental investigation in which deformations due to shrinkage were measured for more than 300 days in the laboratory. The curvatures due to shrinkage were found to be different in cracked and uncracked states. The introduction of compression reinforcement was found to reduce the shrinkage curvatures, whereas increase in tension reinforcement was found to increase shrinkage curvatures. Equations presented here for computing these deformations compare fairly well with experimental data and are recommended to be used in the serviceability analysis of concrete members.
