The efficiency of fluid viscous dampers (FVDs) in enhancing a low-rise Construction Domestic Reinforced-concrete Building's Seismic Performance

The current study aims to investigate the efficiency of fluid viscous dampers (FVDS) in enhancing a low-rise construction domestic reinforced-concrete building's seismic performance. The study conducted in Bangladesh from June 2023 to June 2024 aimed to understand the operation, design specifications, and effectiveness of fluid viscous dampers in mitigating seismic activity. The study used a real-world example of a building retrofit project and used E-Tabs software to create a detailed 3D FEA model of a 10-story structure. The study aimed to assess the ways in which fluid viscous damping systems can improve a structure's seismic resilience, potentially leading to more efficient building techniques in seismically active areas. The study found that FVDs reduce deformity in buildings by absorbing and dispersing earthquake energy, preventing damage. The installation of dampers significantly improved a building's seismic response, increasing stability and safety during earthquakes. This resulted in a safer atmosphere and longer structural lifespan. Overall, the installation of dampers significantly improves a building's seismic response. FVDs reduce natural vibration periods, reducing seismic risk. Buildings with FVDs have lower story shear forces, allowing them to withstand seismic forces without severe damage. Without dampers, buildings show higher story drifts, indicating potential damage. FVDs increase structural stiffness and decrease story displacements, demonstrating the effectiveness of dampers in controlling seismic forces, ensuring structural alignment and integrity during earthquakes.
