En la investigación que se describe en este artículo, se ensayó un segundo espécimen denominado EM2-I, en la misma mesa vibradora y con el mismo registro empleado en la investigación anterior. El espécimen EM2-I, tuvo la misma superestructura que el espécimen EM2, pero con aisladores de base del tipo doble péndulo de fricción. La máxima distorsión de entrepiso medida fue igual a 5.3% y 0.97% para los especímenes EM2 y EM2-I, respectivamente. La máxima distorsión global medida fue igual a 4% y 0.63% para los especímenes EM2 y EM2-I, respectivamente. El máximo coeficiente sísmico medido en la superestructura aislada fue igual al 26 % del máximo valor medido en el espécimen EM2. Los resultados encontrados en esta investigación muestran la importancia del uso de estructuras aisladas como una solución eficiente para que después de terremotos las estructuras puedan ser ocupadas de manera inmediata.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Shaking table tests were conducted in previous research at the National University of Mexico (UNAM) on a miniature steel building named EM2, using a strong ground motion record. This building represented a conventional building. This paper describes the results of a second test unit called EM2-I, tested in the same shaking table with the same ground motion used in the test of EM2. The test unit with isolators, EM2-I, had a superstructure identical to that of the test unit EM2 but with base isolators of double friction pendulum type. Measured maximum interstory drifts were equal to 5.3% and 0.97% for test units EM2 and EM2-I, respectively. Measured maximum global drift was equal to 4% and 0.63% for test units EM2 and EM2-I, respectively. The maximum seismic coefficient measured in the isolated superstructure was equal to 26 % of the maximum value for this parameter measured in test unit EM2. Implications of the results in this research are discussed in this paper, showing the importance of using isolated structures as an efficient solution for resisting strong earthquakes and capable of immediate occupancy.]]></p></abstract>
