%0 Journal Article %T Reinforced Concrete Section Design to Bending According to EN 1992-1-1/2004每EUROCODE2 %A Bogdan Roˋca %A P. Mihai %J Bulletin of the Polytechnic Institute of Jassy, Constructions, Architechture Section %D 2009 %I Gheorghe Asachi Technical University of Jassy %X In the next decades the design of the civil structures will be ruled by Eurocodes. For reinforced concrete structures the Eurocode2 will became of paramount importance to the design of the structural members. An important aspect of designing represents the relation between stress and strain to the design of the section for structural members. In this respect the EC2 defines 14 classes of concrete with different stress每strain relationships. The first stress每strain relation mentioned of EC2 for design is the parabola每rectangle stress distribution on concrete section, and further the simplified rectangle stress每strain shape is mentioned. Therefore, an aspect of the design, poorly emphasized in the national rule, is the design considering parabola每rectangle stress distribution on concrete section. The exposed issues in this paper concern with the design of the reinforced concrete section subjected to bending using two stress每strain relationships mentioned by EC2, and the differences are underlined. The design to bending using parabola每rectangle stress distribution for rectangular section is largely presented, and also the reliability for a fast designing is emphasized. Design relations for a parabola每rectangle stress distribution on section are mentioned. Also, aspects about the boundary between the single reinforcing domain and the double reinforcing domain are emphasized. %K Reinforced concrete %K design section %K bending %K Eurocode2 %U http://www.bipcons.ce.tuiasi.ro/Content/ArticleInformation.php?ArticleID=155
