Abstract: Dampers helps in reducing the vibrations caused by wind and earthquake. By using dampers we can improve the resistance of building towards the forces which are caused by earthquakes .In this study an attempt has been made to compare the results of equivalent static method and response spectrum method of seismic analysis for various models with different combination of dampers providing in different directions and at different story levels. Results shows that usage of dampers increase in base shear.. As base shear increases the resistance of building increases towards earthquake forces. When compared to Response Spectrum method Equivalent static method shows best results.

Keywords: Equivalent Static Analysis1, Response Spectrum Analysis 2,Base Shear 3,, Dampers4.
