Relation endommagement perméabilité pour les bétons. Application aux calculs de structures

Abstract : The relation between damage and permeability is of great importance to evaluate the consequences of a mechanical loading on the hydraulic integrity of sensitive concrete structures like containment buildings of nuclear power plants. An elastic plastic damage constitutive law for the mechanical behaviour is first developed. The model is validated on elementary and structural applications with a special focus on the efficiency of the numerical tools (tangent matrices). A relation between water saturation (drying), damage and permeability is then proposed, based on theoretical and experimental observations. Finally, a Representative Structural Volume of a containment vessel is studied to highlight the influence of hygro – mechanical loading on the hydraulic behaviour (distribution of gas pressure).
