Resumo


El uso de amortiguadores de líquido sintonizado se presenta como una alternativa atractiva para la reducción de la vulnerabilidad de estructuras civiles sometidas a la acción sísmica debido a su simpleza y practicidad en las etapas de fabricación, instalación y mantenimiento. Por otra parte, de manera reciente se ha realizado una propuesta de implementación, denominada Amortiguador de Líquido Sintonizado de Alta Frecuencia, que permite hacer que los dispositivos de control mencionados sean efectivos en estructuras de periodos bajos o dinámicamente rígidas. En el presente trabajo se evalúa de manera numérica la capacidad de este nuevo dispositivo para reducir la fragilidad de una estructura con frecuencia relativamente elevada mediante una serie de análisis sísmicos, demostrando la efectividad para controlar la respuesta dinámica de la estructura analizada.
