In this paper a local bi-linear shear stress-slip law with softening is proposed on the basis of an experimental investigation which reproduces the interface calcarenite-CFRP behavior according to several codes. The parameters were calibrated on the experimental results relative to double shear pull tests from which the maximum transferable load in the joint and the strain profiles were obtained. A numerical investi- gation was carried out by a finite element software including an interface element modeling interlaminar fail- ure and crack initiation and propagation, in order to validate the calibration of the parameters defining this in- terface law and the accuracy of the recorded measurements.
