This research is studying the response modification factor of RC frames by studying the effect of number of stories and the relative inertia of beam to column on the ductility of the reinforced concrete frameswhich have a significant effect on the response reduction factor by performing non-linear static analysis, thencomparing these values with the mentioned values of same RC frames in ECP.In addition, a verification analysis was conductedto guarantee the calculation method of the R-factor. The change of the R-value affects the top plastic displacement and the seismic gap as well. The study shows the difference between seismic gap values using the R-factor resulted from the study and the mentioned values in the ECP using the SRSS method for seismic gap calculation. Based on the study results, the conclusions illustrate the base shear, displacement, ductility and seismic gapchange due to using different R-values for same system
