MICROPRESTRESS-SOLIDIFICATION THEORY FOR CONCRETE CREEP. II: ALGORITHM AND VERIFICATION

This paper presents a numerical algorithm for the microprestress-solidification theory developed in a companion paper and verifies this theory by comparisons with typical test data from the literature. A model for cracking is incorporated in the algorithm.
