Due to limited space, it is now necessary to create higher structures in metropolitan areas. However, as a building's height increases, its natural frequency decreases, which in turn causes it to respond more quickly to dynamic loads like Earthquakes. The building's and its residents' safety are gravely jeopardised by this. Installing fluid viscous dampers in the structure is a popular solution to this issue since they are efficient at controlling vibration and stabilizing the structure under dynamic loads. The purpose of this research is to assess the efficiency of fluid viscous dampers at different placements in reducing earthquake-induced structural vibrations. The findings are compared for three distinct damper placement scenarios: alternately on all stories, on all stories, and on three levels (top, bottom, and center) for a G+20 story framed building. The best model has been compared by two conventional damper placements: first ten stories continuous and first ten stories alternate. The performance of the structure has been assessed in terms of displacement, drift, and shear values during the study. The findings prove that the displacement, drift, and shear values of the structure under Earthquake loads are decreased by the employment of fluid viscous dampers. The most efficient way to lessen the building's seismic reaction is to install dampers on every story. The results of this research may be used to improve the seismic performance of structures and provide useful insights into tall building design and construction in Earthquake-prone locations.
