Currently, there are a large number ofold educational institutions still in operation that were built without considering earthquake-resistant criteria. These buildings, being considered essential, must maintain their operability during and after a seismic event. In this research, two two-level modules with regular plans belonging to an educational institution built in 1994 were analyzed. These modules are characterized by having a reinforced concrete frame system in the X direction and a confined masonry system in the Y direction. These modules were analyzed by applying the linear parameters of NTP E.030 and nonlinear methodologies such as the Nonlinear Dynamic Analysis (NDA), where the structures were subjected to three seismic events that occurred in Peru, which were corrected, scaled, and matched to the response spectrum using Seismosignal and Seismomatch software. ETABS software was...
