Resumen: The objective of this work is to apply an optimization technique based on the use of a Genetic Algorithm to evaluate the minimum reinforcement in lightly reinforced concrete (LRC) beams for given material properties, geometry and loading conditions. It adopts the effective slip length model, which reproduces numerically the mechanical response of a given reinforced beam, as the tool that generates fitness values needed by the GAs procedure. The speed and accuracy of the model compensate with the large amount of calculations required by GAs. The methodology is demonstrated through the searching of minimum ratio for a reinforced prismatic beam loaded at three points at various conditions.
