The technique has some limitations that, theoretically, reduce its efficiency, such as in tall buildings and soft soil conditions. In this paper, a non-conventional seismic isolated structure is studied to evaluate the benefits of the technique on it. Specifically, a stadium grandstand located in Colombia with hard and soft soil conditions beneath the isolated base is analyzed. The considered structure is important due to its necessity for seismic risk mitigation. It will have a high number of people to evacuate safely during earthquakes, and after them, it could be designated as a humanitarian shelter. The results a) show structural benefits principally in hard soil conditions, b) corroborate and quantify the limitations in soft soil, and c) make recommendations to isolate structures under the conditions studied here.]]></p></abstract>

La técnica, teóricamente, tiene limitaciones de uso por eficiencia, como en edificaciones altas y suelos blandos. En este artículo se estudia una estructura aislada no convencional, para evaluar los beneficios del aislamiento sobre esta. Específicamente se analiza una tribuna de estadio localizada en Colombia, con condiciones de suelo duro y blando. La estructura es importante, debido a su necesidad de mitigación del riesgo por sismo. Esta considerará un alto número de personas que deben evacuar de forma segura durante terremotos y después de estos, la estructura podría ser destinada a refugio humanitario. Los resultados a) muestran beneficio estructural principalmente en condiciones de suelo duro, b) corroboran y cuantifican las limitaciones de los suelos blandos y c) permiten generar algunas recomendaciones para aislar estructuras bajo las condiciones aquí estudiadas.]]></p></abstract>
