CRITERIA FOR RATIONAL PREDICTION OF CREEP AND SHRINKAGE OF CONCRETE

This paper examines various basic questions in formulating and evaluating a prediction model for creep and shrinkage of concrete. Verification by comparisons to a few subjectively selected data sets is no longer justifiable because computers have made statistical comparisons to the existing internationally accepted comprehensive data bank very easy. Yet, there are three criteria to be considered: 1) After optimizing its coefficients, the prediction model should be capable of providing close fits of the individual test data covering a broad range of times, ages, humidities, thicknesses; 2) the model should have a rational, physically justified theoretical basis; and 3) should allow good and easy extrapolation of the short time tests into long times, at high ages of loading, large thicknesses etc.
