With the purpose of addressing excessive displacements between floors that affect the functionality of the structure after a seismic event, the present investigation compares the seismic behavior of a critical building reinforced with BRB and SLB seismic dissipators through a nonlinear time-history analysis. In the case study, a target drift of 0.0035 has been set. An analysis of Pavilion “A” of the José Casimiro Ulloa Emergency Hospital (HEJCU), located in Miraflores, Lima, was carried out to determine the displacements and drifts of the soil, and evaluate the need for the two proposed reinforcement options. Subsequently, BRB heatsinks were used to model the structure. From the data obtained on plant drifts, displacements and accelerations, an average of 0.72% in drifts, 0.85 cm in displacements and 0.53 g in accelerations was calculated. Subsequently, the SLB heatsinks were used to carry out the seismic analysis. From the data obtained, it has been verified that the average drift-displacement and ground accelerations are 0.54%, 0.65 cm and 0.42 g, respectively, that are considered acceptable. It is imperative to know the capacity of the structure and the level of demand it will face to evaluate the performance of the existing structure (as-built), reinforced with BRB and SLB. In order to determine which reinforcement option is used by the critical building to fulfill its functionality during and after a seismic event, a nonlinear analysis will be performed in the time domain, considering the nonlinearity of columns and beams with BRB. and SLB. For the nonlinear time domain analysis, seven seismic spectra were used to examine the two reinforcement options. The results confirm that the use of BRB heatsinks in the same configuration reduces ground drifts, which improves both the functioning and operability of vital facilities and the ability to respond more effectively to seismic movements.
