The coastal zone of Peru is exposed to a high seismic risk, and many essential constructions in the country still lack seismic protection systems. This increases the likelihood of these structures experiencing considerable damage in the event of a severe earthquake, potentially leading to collapse. The present research proposes the implementation of Taylor-type viscous fluid dampers and Bozzo-type Shear Link metallic dampers, through two different designs applied to the same case study involving a reinforced concrete structure in the pavilion of a typical school built on soft ground in Lima. For this purpose, a spectral modal dynamic analysis of the building without dampers was conducted, as well as a linear time-history dynamic analysis of the structures with dampers. The results of these analyses provided the displacements and drifts of the structures. It was observed that the conventionally designed structure does not exhibit adequate structural behavior in the face of a severe earthquake, unlike the structures with damper implementation, which showed a significant reduction in their drifts and displacements. However, it was emphasized that the structure with the implementation of metallic dampers exhibited better structural behavior compared to the structure with viscous fluid dampers.
