One of the critical structural failures in buildings is the phenomenon of punching shear in the slab-column connection. In this paper, a nonlinear numerical model for studying this phenomenon in reinforced concrete slabs is presented. The model is based on FEM and developed in ABAQUS. The ultimate goal is to prepare a simulation tool to study existing slabs, assess their punching strength and design a reinforcement if necessary. The study also concerns new constructions, where geometry and ratios could be optimised. For that reason, the automation of routines in Python code has been carried out in order to improve the efficiency in the creation of a variety of numerical models.
