The destruction of the supporting zone due to punching and the lack of adequately constructed reinforcement may result in a progressive catastrophe. Instructions concerning the prevention of such situations are to be found only in CSA A23.3 (2011) and ACI 318 (2004). The present paper deals with a model of calculations which permits to assess the values of reserves of the load-bearing capacity of the supporting zone after its destruction by punching. The presented considerations are based on results of experimental investigations carried out on reinforced concrete models of slab-column connections in the scale 1:1. The model of calculations permits to assess the values of the forces of the load, at which the bars situated immediately in the supporting zone fail. This model was verified basing on the results of experimental investigations, performed on simplified tested models.
