This paper describes the proposed reinforcement of the building of the Legislative Assembly of El Salvador, where the layouts of fluid viscous dampers influence in their effectiveness for seismic protection of building. The effectiveness is measured by less interstory drifts, more supplemental viscous damping ratio, and less damper forces. The building was analyzed for each layout of fluid viscous dampers taking into account the studies realized by different researchers about the supplemental damping ratio. Three pairs of acceleration time histories were scaled in any manner which they are compatible with the design spectrum El Salvador. Two of the ground motions were the earthquakes that occurred on 10 October 1986 and 13 January 2001. After time history analyzes, it was determined that the best alternative of reinforcement of building is the layout Upper Toggle Brace. Although the interstory drifts are relatively smaller for building with layout Lower Toggle Brace than for building with layout Upper Toggle Brace, as well as the damper forces, the layout Toggle Upper Brace is chosen as a solution to reinforcement of building, due to higher additional damping is achieved, thus the reinforcement of columns and beams were not necessary and the initial request was satisfied, not interrupt the activities into the building.
