Analytical Model for Assessing Reinforced Beams

Article Preview

Abstract:

This study presents an analytical model for assessing reinforced simply supported beams based on recommendations of the Brazilian Concrete Norm (NBR-6118) and a study published by the International Federation of Concrete (fib). Rectangular and “T” sections are only considered in this study. The beam’s deformation depicted the diagram of moment curvature in regard with the limits of materials deformation in the elastic state is also explored. The results obtained by both Norms were complement with each other, revealing great similarity. Furthermore, destructive tests of reinforced beams made in the laboratory were compared with those obtained by the analytical model, showing excellent performance of the proposed model. The objective of this publication is the presentation of the analytical model. Analysis of comparing the results between the analytical model and from field tests were presented in another publication that will be mentioned in this study.
