We start from a standard element in witch we add degrees of freedom to allow the slip description. The cracking of the concrete is treated in the frame of incompatible modes method, with a displacement jump at the crack position, to be able to compute the crack opening. The bond slip is modeled with a DruckerPrager law, to be able to take into account the influence of confinement over the friction between the steel and the concrete. One shows that the modeling of the bond slip behavior is necessary to predict the crack spacing and the crack opening in reinforced concrete structures under severe loading like earthquake for example. And this is important for deduced properties like leaks when we are interested to permeability, or damping by friction witch is important in seismic simulations. .
