Abstract: This article presents a part of EDF’s efforts to understand and model the aging of double wall concrete containment buildings of its nuclear power plants. These concrete walls are prestressed walls which must remain leak-tight during the service life of the structure. As a part of this effort a 1/3 mock-up called VeRCoRs has been built for experimental purpose.
Creep and shrinkage induce a decrease of the leak-tightness which must be understood and modeled. Therefore, drying creep and shrinkage constitutive laws are used to model the CBBs. In this paper the identification of these constitutive laws in a non-isothermal context is detailed, and an example of application is shown on the mock-up inner wall.
