ANALYSIS OF BUILDING WITH AND WITHOUT DAMPERS USING ETABS SOFTWARE

This project investigates the seismic behaviour of symmetrical and unsymmetrical G+26 buildings with and without Fluid Viscous Dampers (FVD) using ETABS 2022 software. The main objective is to evaluate the impact of FVDs on reducing seismic response, considering various damping device positions, shapes, and building heights. The study involves nonlinear time-history analysis using Electro data and seismic evaluations based on the equivalent static and response spectrum methods. The building is analysed for seismic Zone IV, medium soil conditions (Type II) as per IS 1893-2016. The study examines how structures, including multi-storey buildings, respond to earthquake vibrations. It highlights the importance of damping devices, like Fluid Viscous Dampers, in controlling seismic energy and reducing structural damage by controlling lateral displacements, shear forces, and bending moments. The analysis compares buildings with and without FVDs, considering factors such as story drift, shear force, and moments, and evaluates the effects of different soil conditions (high, medium, and loose). Results indicate that Fluid Viscous Dampers significantly improve the seismic performance of buildings, particularly in reducing story drifts, base shear.
