Comparative Study on Seismic Analysis of RC Framed Building with Fluid Viscous Dampers and X-Bracings

  • Abstract:
  • This study investigates the seismic behaviour of adjacent RC framed buildings with and without supplemental damping systems—Fluid Viscous Dampers (FVDs) and X-bracings—under severe earthquake loading. Using ETABS modelling and IS 1893:2016 guidelines, three building configurations—a bare frame, an FVD-connected frame, and an X-braced frame—were analysed in seismic Zone V over medium soil conditions. Key performance indicators such as time period, base shear, storey drift, and displacement were evaluated. The bare frame showed the highest vulnerability to pounding effects, with significant displacement and drift. FVDs improved energy dissipation and reduced drift without major stiffness enhancement, making them suitable for retrofitting. X-bracing significantly improved stiffness, minimized displacement and drift, and offered superior control of base shear. Results confirm that X-bracing is the most effective for enhancing seismic resilience in adjacent high-rise buildings with limited separation, while FVDs offer flexibility for diverse applications.
