To contribute to a better understanding of the behavior of these slabs were fabricated in the laboratory 8 one-way reinforced concrete ribbed slab panels where the main variables were the distance between the ribs and the thickness of the flange. The normative recommendations of NBR 6118, ACI 318 and EUROCODE 2 for the ultimate resistance of these slabs were evaluated. The experimental results showed an increase of shear strength with increasing thickness of the flange, also resulting in greater reinforcement strains and higher deflections.Acesso AbertoResistência ao cisalhamentoLaje nervuradaConcreto armadoNormas técnicas (Engenharia)Estrutura de engenhariasVigas de concreto armadoFissuraArtigo de Periódico
