Projects with seismic isolation are increasing at Peru, even the Peruvian Seismic Standard establishes that seismic isolators must be used in hospitals located in seismic zone 4 and 3 of Peruvian seismic map. Is also accepted that there may be isolated buildings on soils S0, S1, S2 and S3. In isolated buildings that are on soil type S3 and in seismic zone 4, maximum displacement values are obtained. This implies the use of flexible connections; in addition in some cases these displacements cause that there is a smaller usable area of the building. One alternative to reduce these displacements is the use of Supplementary Viscous Dampers in the base of isolated building which adds damping to isolation system. In this research, a mathematical model of a 5-story building with elastomeric isolators, located in seismic zone 4 and soil type S3 was evaluated. This model was then analyzed with Supplementary Viscous Dampers, considering 5 different conditions of critical damping ratio: 15%, 30%, 45%, 60% and 75%. For all analyzes, 7 time-history records compatible with Peruvian seismicity were used. Displacement reductions of isolated base were obtained up to 30% of its initial value. The variation of responses (Accelerations, Drifts, Shear Forces, and Dissipated Energy) was analyzed as a function of the damping increasing. It was verified that the Peruvian seismicity combination of isolators and dampers tends to increase the seismic responses of the superstructure.
