“…Gasparini [10] states that the credit for the development of this system should be given to George M. Hill, an engineer who reportedly designed and built constructions like filtration plants and storehouses in different regions of the United States between 1899 and 1901. He emphasizes, however, that C A. P. Turner, an American inventor and engineer, was the one responsible for demonstrating that these slabs were reliable with numerous buildings constructed, the first being Johnson-Bovey building in the city of Minneapolis in 1906.…”

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.O dimensionamento à punção é um ponto crítico no projeto de lajes lisas e devido à falta de um método teórico capaz de explicar este fenômeno a verificação da capacidade resistente de ligações laje-pilar é feita normalmente utilizando-se as recomendações de normas de projeto. Este artigo discute aspectos relevantes do surgimento do sistema de lajes lisas, dos fatores que influenciam na resistência à punção de lajes sem armadura de cisalhamento e faz comparações entre os resultados experimentais de um banco de dados com 74 lajes cuidadosamente selecionadas com resultados teóricos utilizando-se as recomendações das normas ACI 318, EUROCODE 2 e NBR 6118 e também através da Teoria da Fissura Crítica de Cisalhamento, apresentada por Muttoni (2008)

“…Equation (1) shows the ACI 318-05 6 expression for square or circular columns of moderate dimensions relative to the thickness of the slab (1) where d is the average flexural depth of the slab, b 0 is the perimeter of the critical section located d/2 from the face of the column, and f c ′ is the specified concrete compressive strength.…”

“…In the US, engineers George M. Hill, Orlando W. Norcross and C. A. P. Turner are mentioned as the most credited for the development of flat slabs. Gasparini [3] said that the contribution to the development of this system should have been given to George M. Hill, an engineer who designed and built facilities such as filtration plants and warehouses in various regions of the United States between 1899 and 1901. Also, he points out that C.A.P.…”
