Resumen

ZUNIGA CUEVAS, Oscar  y  TERAN GILMORE, Amador. Control de aceleraciones de entrepiso para sistemas estructurales con aislamiento sísmico de base. Ing. sísm [online]. 2012, n.87, pp.25-45. ISSN 0185-092X.

The dynamic response of a series of base-isolated structures subjected to ground motions that were recorded on firm soils located in the Mexican Pacific coast was studied to understand the influence of their structural properties on the floor acceleration demands. The structural systems were considered elastic and the dissipating energy capacity of the isolation system was represented through a viscous damping model. The damping difference between the super-structure and the seismic isolation system was considered through a non-classical damping approach. Upon identifying the effect of the structural properties that are able to control the floor acceleration demands, an equivalent single-degree-of-freedom system is discussed to conceive base-isolation systems for low-rise structural systems.
