Abstract: This paper presents numerical simulation of early age deformation and cracking of RC structures with full 3D multi-scale and multi-physical integrated analysis. First, a multi-scale constitutive model of solidifying cementitious materials is briefly introduced based on systematic knowledge coupling microscopic thermodynamic phenomena and microscopic structural mechanics. Then, model validations are done by applying the multi-scale and multi-physical integrated analysis system to the early-age behavior of small sized specimens, full-size RC deck slab specimens, and real RC slab decks to be constructed. Through experimental validation and full-scale numerical simulation, factors affecting cracking generation and propagation are identified.
