This article aims to the comparison of different parameters for defining the interface characteristics between flat slab without transverse reinforcement and reinforced concrete overlay in non-linear analysis. The input parameters for the interface are stiffness, tensile strength, friction coefficient and cohesion. These coefficients represent uncertainties in non-linear modelling. Non-linear model was developed in ATENA 3D software and simulates punching shear of flat slab without shear reinforcement strengthened by concrete overlay. Two types of interfaces are considered: without reinforcement crossing the interface and with shear reinforcement crossing the interface. Parametric study shows, how different values of interface parameters influence the final punching shear capacity of representative model. Numerical models will be used as a prediction for experimental results of specimens.
