India suffered from many earthquakes over last some decades. Analysis of those earthquake showed that large number of existing structures needs to be upgrade for seismic actions. Performance based earthquake engineering is recent focus of researchers. Present study focused on the seismic retrofitting of existing structures which are previously designed for gravity loads only, by using performance based design philosophy of friction damper. Storey displacement, inter-storey drift, axial force, maximum moment, maximum shear force, base shear variation and effectiveness of dampers are observed for each model and in each direction for seven records of time history earthquakes. Results showed that response of structure are well within the limits of codes provisions. Thus friction damper can be used effectively for seismic retrofitting of structures.
