Abstract: Earthquakes are the largest natural hazard in damaging the structures. The structural response control is necessary to create the safer structures against earthquakes. Vibration control systems are used to transfer the lateral loads imposed on a structure to the foundation. To reduce the dynamic response of the structures due to earthquake loading friction dampers are used. The present work deals with a 10 storey RCC building with square and rectangular columns with the square and rectangular shape of the structure was analyzed with and without friction damper in ETABS 2016. Four different cases of buildings with and without friction damper have been analyzed in ETABS 2016. The study performs response spectrum analysis and nonlinear time history analysis on these buildings. The time history data of Bhuj earthquake is used in the analysis. In the present study the effectiveness of friction damper in reducing the responses of a structure is evaluated. The responses of the structure in terms of pseudo spectral acceleration, pseudo spectral velocity and spectral displacement have been compared with and without friction damper.
