Abstract

In this paper, five storey RC (Reinforced Concrete) building is retrofitted using friction damper and steel bracing methods to achieve a target seismic performance level in terms of inter-storey drift and plastic hinge rotations. Firstly, a static pushover analysis is performed to get the required damping value for the target performance limit. Then a friction damper is designed for this required damping value. To study the effectiveness of friction damper, a time history analysis of building is performed using scaled time history compatible with IS 1893 response spectrum (zone V, soil type 1) in SAP2000 v20. To bring inter-storey drift to the permissible limit, steel bracing along with friction dampers are used. Further response spectrum analysis is carried out to compare the results of storey displacement, drift with that of time history results. So, the combination of friction damper and steel bracing is found to be effective in retrofitting five storey RC buildings.
