VL - 24 IS - 40 SE - DO - 10.19053/01211129.4024 UR - https://revistas.uptc.edu.co/index.php/ingenieria/article/view/4024 SP - 31-40 AB - <span>The compressed steel in a doubly reinforced beam improves ductility, reduces immediate and long-term deflections, it is available to support the tension in sections under reversal stress, and in low-height beams, it increases strength. With the expected strain as a measure of the section ductility, the paper proposes a direct methodology to determine the necessary compression quantities and tension reinforcement. It finds that the most efficient sections are those for which the tension reinforcing strain is 0.005.</span> ER -
