Multi-scale Modeling of Concrete Performance Integrated Material and Structural Mechanics

Abstract

Multi-scale modeling of structural concrete performance is presented as a systematic knowledge base of coupled ce-mentitious composites and structural mechanics. An integrated computational scheme is proposed for lifespan simulation of reinforced concrete. Conservation of moisture, carbon dioxide, oxygen, chloride, calcium and momentum is solved with hydration, carbonation, corrosion, ion dissolution, damage evolution and their thermodynamic/mechanical equilibrium. The holistic system is verified by the reality.
