 Summary:
 The paper presents a short brief of historical development of flat slabs and mechanical models for describing the behavior of the slab around the column exposed to punching. The procedure for calculating the failure load of the of reinforced concrete slabs without the shear reinforcement according to the Eurocode is described in detail, and the numerical calculation was carried out for 11 slabs. The slabs are supported on all four edges, and loaded over centric square column. The variables of these slabs were the strength of the concrete on the pressure and the amount of the longitudinal reinforcement. The obtained results are compared with the existing measured results.
