| 要旨 | Due to a lack of an adequate analysis tool, structural design is still formally separated from durability design, despite the well accepted fact that there is a strong interaction between degradation of the material due to mechanical loading and structural performance under harsh environments. A critical need exists to establish the essentials of this dependence between mechanical performance and the physico-chemical environment. A method is proposed for the development of this tool within the general framework of continuum thermodynamics of reactive porous media. Such an energy approach allows one to account in a consistent way for the many different quantities affecting the mechanical and transport properties of the material. The usefulness of such an approach is illustrated through the classical case of a reinforced beam subjected to both mechanical loading and chloride ingress, where the interaction between these two deterioration mechanisms is shown to have a major impact on the long term performance of the beam. |
