Analysis and Design of Multi-Storey Buildings with Dampers for Improved Earthquake Resistance

The project investigates advanced seismic protection for medium-rise structures, specifically a G+5 Reinforced Concrete (RC) building, situated in high-risk zones such as Seismic Zone IV of the Indian Standard IS 1893. Traditional seismic design methods, which increase stiffness and strength, often lead to heavier members, higher costs, and increased seismic forces. This research focuses on utilizing Fluid Viscous Dampers (FVDs), a passive energy dissipation technology, to enhance seismic resilience. These dampers convert earthquake-induced kinetic energy into heat, providing substantial supplemental damping. The study employs the software ETABS to create a detailed analytical model, performing comparative analysis of the building's seismic performance with and without viscous dampers under design-level earthquake loads. Key engineering demand parameters (EDPs) such as inter-storey drift, base shear, storey displacement, and energy dissipation will be evaluated. The research aims to quantify the reduction in structural demands and establish a practical methodology for integrating dampers into medium-rise buildings in high-seismic region.
