Los resultados numéricos obtenidos fueron comparados con resultados experimentales, mediante el cálculo de la energía disipada por los muros estudiados, Además, se valuó el comportamiento de los &#8220;disipadores de energía&#8221; del muro, formados por barras de acero corrugado, que pasan a través de la junta entre el muro prefabricado y la cimentación. Otro elemento importante es el cable de acero de presfuerzo, que atraviesa al muro mediante un postensado, en toda su altura, desde el extremo superior del muro hasta la base de la cimentación. El cable de postensado, es el que genera en el muro un comportamiento de recentrado, que combinado con los &#8220;disipadores de energía&#8221; logran un sistema que puede controlar desplazamientos excesivos, con daños poco relevantes. Se emplearon los resultados experimentales reportados por Smith et al. (2012), y Rahman y Restrepo (2000) de muros híbridos sólidos rectangulares, HW1 y HW3, respectivamente. Adicionalmente, se realizó una comparación de la cantidad de energía disipada, entre los muros analizados y muros convencionales monolíticos, de dimensiones y características similares.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT In this paper, an energetic approach is used to validate some numerical models that can represent the global response of hybrid walls under the action of reversible cyclic lateral loads. The numerical results obtained were compared with experimental results by calculating the energy dissipated by the walls studied. In addition, the behavior of the wall's "energy dissipators" was evaluated, formed by corrugated steel bars, which pass through the joint between the prefabricated wall and the foundation. Another important element is the prestressing steel cable, which crosses the wall by means of post-tensioning, throughout its height, from the upper end of the wall to the base of the foundation. The post-tensioning cable is what generates a recentering behavior in the wall, which combined with the "energy dissipators" achieve a system that can control excessive displacements, with little relevant damage. The experimental results of rectangular solid hybrid walls reported by Smith et al. (2012) and Rahman and Restrepo (2000) were used, HW1 and HW3, respectively. Additionally, a comparison was made of the amount of energy dissipated between the analyzed walls and conventional monolithic walls, of similar dimensions and characteristics.]]></p></abstract>
