Abstract: The interface behaviour between steel and concrete, during pull-out tests, is numerically investigated using an interface model coupling adhesion and Coulomb friction. This model, first developed by Raous, Cangemi, Cocou and Monerie (RCCM), is based on the adhesion intensity variable, introduced by Fremond, which is a surface damage variable. The RCCM model is here completed by taking a variable friction coefficient to simulate the slip weakening of the interface when sliding occurs. Identification of the parameters and validation of the model are carried on pull out experiments conducted at the INSA of Toulouse on steel-concrete interface of reinforced concrete.

Keywords: Coulomb friction; adhesion; steel–concrete interfaces; non-smooth mechanics; interface behaviour; steel; reinforced concrete; surface damage; slip weakening; sliding.
