Abstract

Creep and shrinkage characterization, and models for predicting its parameters, are analyzed, and a new simplified model is proposed. Extensive graphical and statistical comparisons with test data available in the literature are made to verify and calibrate the model. The deviations of predictions made using existing ACI and CEB models from the same data are also determined. The coefficients of variation and 95 percent confidence limits of the deviations from test data are evaluated. A detailed practical example of a segmental box girder bridge is given.
