Joint shear behavior is rediscussed on the basis of a 2D statistical characterization and a 3D modelling of a joint roughness morphology. The shear processes and progressive degradation phenomena on the joint surfaces are analyzed in relation with normal stress and shear displacement. These discussion and analysis are based on the results of an experimental study on the shear behavior of unfilled natural rock joint replicas
