Resumo: This work presents a study on the analysis of reinforced concrete beams in which the physical non-linearity of the material is implemented through the refined procedure in the Technical Comments of Brazilian code NBR-6118 - CT 301 / Ibracon. This model considers the physical non-linearity of the reinforced concrete through momentum-curvature diagrams of a cross-section. The momentum-curvature diagram presented in the CT-301 (2003) uses medium deformation in the reinforcement, in which the tension stiffening of the reinforced concrete is taken into account. Using programming language Fortran Power Station, the expression given by the code for the contribution of the tension stiffening of the reinforced concrete was implemented. Finally, some results are presented to check the validity of the employed calculation process

Este modelo considera a não-linearidade física do concreto armado via diagramas de momento x curvatura de uma seção transversal. O modelo de diagrama momento x curvatura apresentado pelos Comentários Técnicos da NBR-6118 - CT-301 do Ibracon (2003) utiliza a deformação média na armadura tracionada, onde se leva em conta a resistência do concreto tracionado entre fissuras (tension stiffening). Portanto, foi implementado, em linguagem de programação Fortran Power Station, o procedimento dado pela norma para a contribuição do concreto tracionado entre fissuras. Para comprovar a validade do procedimento implementado, são realizados exemplos numéricosUniversidade Estadual De Maringá2008-05-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/318010.4025/actascitechnol.v30i1.3180Acta Scientiarum.
