AB  - This contribution aims at improving the finite element modeling of concrete’s damage- permeability coupling using continuous and elastic-based damage approaches. Accordingly, a review of existing laws is achieved showing how they lack physical representativeness in terms of (a) permeability evolution from a microcracked (homogeneous) state towards a macrocracked (discrete) one and (b) permeability evolution considering mechanical loading-unloading paths. To resolve those issues, a new strain-based (rather than damage based) permeability law is suggested. The validation of this new law is achieved through two applications: (a) at the specimen scale and based on analytical developments where the permeability of the BIPEDE…
