Optimizing the Positioning of Fluid Viscous Dampers to Enhance Resilience of Tall Buildings against Earthquake-Induced Structural Vibrations-A Review

Abstract: This study explores the effectiveness of Fluid Viscous Dampers (FVDs) in mitigating vibrations caused by lateral loads, such as earthquakes, in high-rise buildings. As urban areas demand taller structures, reduced natural frequencies make buildings more vulnerable to dynamic forces. The research evaluates a G+19-story reinforced concrete (RC) building using code-based methods to assess seismic responses, including lateral displacement, drift, base shear, and energy dissipation. Various FVD arrangements and quantities were analyzed to identify optimal placements for maximizing drift reduction, energy dissipation, and cost efficiency. Findings reveal that installing FVDs across all stories significantly reduces displacement, drift, and shear values, enhancing the building's seismic resilience. This study underscores the critical role of strategic damper placement in improving the performance and safety of tall structures in earthquake-prone regions, offering practical insights for designing earthquake-resistant buildings.
