Strain method for doubly reinforced rectangular beams design
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,...

| description | 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. |

El acero en compresión en una viga doblemente reforzada mejora la ductilidad, reduce las deflexiones instantáneas y de largo plazo, está disponible para tomar la tracción en secciones sometidas a reversión de esfuerzos y, en vigas de poca altura, aumenta la resistencia. A partir de la deformación unitaria esperada del acero en tracción, como medida de la ductilidad de la sección, se propone una metodología directa para determinar las cantidades de refuerzo necesarias, tanto en compresión como en tracción. Se establece que las secciones más eficientes son aquellas para las cuales la deformación en el acero en tracción es 0.005.
