Microprestress-Solidification Theory for Concrete Creep. II: Algorithm and Verification

Publication: Journal of Engineering Mechanics
Volume 123, Issue 11

Abstract

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.
