SACRAMENTO, P. V. P.; FERREIRA, M. P.; OLIVEIRA, D. R. C.  and  MELO, G. S. S. A.. Punching strength of reinforced concrete flat slabs without shear reinforcement. Rev. IBRACON Estrut. Mater. [online]. 2012, vol.5, n.5, pp.659-691. ISSN 1983-4195.

Punching strength is a critical point in the design of flat slabs and due to the lack of a theoretical method capable of explaining this phenomenon, empirical formulations presented by codes of practice are still the most used method to check the bearing capacity of slab-column connections. This paper discusses relevant aspects of the development of flat slabs, the factors that influence the punching resistance of slabs without shear reinforcement and makes comparisons between the experimental results organized in a database with 74 slabs carefully selected with theoretical results using the recommendations of ACI 318, EUROCODE 2 and NBR 6118 and also through the Critical Shear Crack Theory, presented by Muttoni (2008) and incorporated the new fib Model Code (2010).

Keywords : flat slab; punching shear; reinforced concrete; codes.
