Unlocking Resilience: Examining the Influence of Fluid Viscous Dampers on Seismic Performance of Reinforced-concrete Structures in Earthquake-prone Regions

Abstract

In high seismicity regions like Algeria, the seismic performance of structures is of paramount importance. This study investigates the effectiveness of fluid viscous dampers (FVDs) in enhancing the seismic resilience of a 12-story (G+12) reinforced concrete structure. By utilizing Etabs and SeismoSoft softwares, a comparative analysis is conducted between two structural configurations: one with a traditional fixed base and another incorporating fluid viscous dampers. The incorporation of FVDs aims to mitigate the seismic impact by dissipating energy, thereby reducing base shear, displacement, and acceleration during seismic events. The structure's location in a high seismicity zone necessitates robust design strategies to ensure safety and structural integrity. This paper presents a comprehensive analysis of the seismic response and advanced simulation framework providing detailed results on key parameters. The findings highlight the potential of fluid viscous dampers to significantly improve the seismic performance of reinforced concrete structures, offering a promising solution for earthquake-prone areas.
