Retrofitting buildings with conventional methods usually include addition of walls, strengthening of the members by increasing their sizes or demolishing entire storeys in order to reduce seismic demands. These methods are often very costly, time consuming and many times less effective. These difficulties lead to invention of many devices which are used to dissipate the energy in a structure during an earthquake event. This paper discusses a retrofitting strategy with a passive energy dissipation device known as Fluid Viscous Damper or FVD. A nine storey RCC frame was analysed using the software ETABS to obtain its seismic behavior without retrofitting and with linear FVD retrofitting and results were compared with respect to peak storey displacements and inter-storey drifts and pseudo spectral accelerations. It was found that retrofitting with FVD significantly reduced the seismic demand.
