Hi I have some question about pile modelling with interface and using shear curves. first of all i want to know how i can estimate ultimate shear force and shear stiffness module for interfaces. second,I need some help about entering shear stiffness module as a function.Im reading a PDF file of tutorial but dont understand what is the parameters of this curve(I have explained in attache pictures).
