The research focuses on the seismic evaluation of Pavilion B of the Luis Negreiros Vega Hospital. The case study was configured with viscous fluid heatsinks in chevron configuration and diagonal configuration. The most representative seismic parameters were evaluated. Among them, inter-story distortions, dissipative forces, the design damping coefficient and mainly torsional irregularities that have a significant impact on buildings. The heatsinks were implemented through the criterion of maximum displacements. That is, they were located where the node displacements were highest. Nonlinear viscous fluid heatsinks with design velocity exponent (𝞪=0.5) were used for modeling. A mathematical model was developed with the ETABS 18 Software. The methodology proposed in foreign codes was used: FEMA and HAZUS. From the design, the optimal damping coefficient of the structure was calculated for both X and Y directions. The analysis of the building was developed with “time-history” input values, defined by the RNE, by three (03) groups of accelerograms horizontals, which were scaled to our elastic design spectrum with SEISMOMATCH Software. From the analysis of the results, it was determined that: at the level of distortions, the heatsinks in chevron configuration are slightly more efficient than the heatsinks in diagonal configuration at the level of analysis per gantry. On the other hand, it was determined that the viscous fluid dissipators, when placed in the nodes with the greatest displacement of the building, significantly reduce the torsional irregularities (𝜟max/𝜟prom) of the structure.
