TY  - JOUR
AB  - This paper assesses the influence of slab continuity on the punching resistance of a realisticallyproportioned flat slab floor plate without shear reinforcement. The edge column punching resistance ofa symmetric flat slab extending bays in each direction was assessed by means of NLFEA with TNODIANA, MC2010 levels II, III, IV, Eurocode 2 and NBR 6118. Both Eurocode 2 and NBR 6118 areseen to give similar predictions for punching resistance, while MC2010, which is based on the CriticalShear Crack Theory and depends on how rotations are calculated and FE modelling assumptions, variessignificantly with its levels of approximation with Level IV agreeing reasonably well with predictionsfrom NLFEA. Direction for the critical rotations is shown to vary and can also be influenced by thereinforcement over the span. For EC2, NBR 6118 and MC2010 LoA II and III punching shear designare independent of span, unlike the results obtained with MC2010 LoA IV.
