Abstract
RC flat slabs are frequently used structural members in building construction. Safety verification and avoidance of failure due to punching in the vicinity of a column is currently performed using empirical model which is introduced in Eurocode 2. However extensive discussions are held about replacement of the EC2 model by more refined mechanical model which is presented in Model Code 2010. The paper deals with statistical evaluation of the safety level above mentioned models for punching resistance without shear reinforcement. Evaluation is supplemented by third model from already cancelled Czechoslovak national standard ČSN 731201. Database which includes results of more than 400 experimental tests of flat slab specimens has been used for the statistical evaluation.
