Evaluación de respuesta estructural de edificaciones flexibles sobre sistemas de aislación sísmica.

Abstract

One of the main objectives of seismic engineering is to protect buildings from the destructive consequences that earthquakes cause. This is why the seismic isolation method has been introduced for years, to protect the superstructure by controlling and/or mitigating the responses generated by earthquakes. However, for high-rise systems, the response of the isolation system is poorly understood, as is that of the superstructure. This work pursues to evaluate the efficiency of isolation systems on flexible structures, for which ten different simplified structural models with fixed base and isolated base have been developed for five seismic records from Ecuador. To study the advantages or disadvantages of introducing seismic isolation concerning maximum displacements, absolute maximum accelerations, and drifts. Additionally, to separately evaluate the behavior of the superstructure and the isolators.
