Multi-Scale Methods for the Analysis of Creep-Damage Coupling in Concrete
Résumé
In civil engineering, the control of creep has a major role in concrete structure design. Indeed, the viscoelasticity of concrete leads to delayed deformations which could be at the origin of cracking in structures. So, these delayed strains have an impact on their safety margin and life time, especially when they are subjected to high loads. For example, underground concrete structures and other infrastructures undergo, during the construction phase, load due to soil pressure, which leads to important creep deformations.
