It should be mentioned that prior to the experimental tests, a numerical model was carried out that allowed determining that plastic hinges of the frame to be rehabilitated were generated in the slit plates of Figure 4 before than in the structural elements.
Es importante mencionar que previo a las pruebas experimentales, se realizó un modelo numérico en donde se pudo determinar que las rótulas plásticas del pórtico a rehabilitar se generaban en las placas ranuradas de la Figura 4 antes que en los elementos estructurales.
