Response reduction factor is invariably used by most seismic design codes to include the non-linear response of structure. The non-linear behaviour of the structure is taken into account due to this factor which permits the designer to use a linear elastic force-based design. Using non-linear static pushover analysis the estimation of seismic response reduction factor for a dual system of reinforced concrete special moment resisting frame(SMRF) and shear walls has been focused on in these study. The design of the frames is done using the Indian standards for seismic and RC design and are subjected to two different lateral load patterns. Based on the push over curve which is obtained between base shear and roof displacement the actual values of Response reduction factor have been worked out. After analysis it was observed that the response reduction factor depends on four major factors, they are Strength factor, Ductility factor, Redundancy factor and damping factor affect and hence this four factors must be taken into consideration while determining the appropriate response reduction factor to be used while designing a building for earthquake resistance.
