Response modification factor (RMF) is the type of seismic design parameters to recognize the nonlinear concert of building structures during solid earthquakes. As such, relying on this factor, various seismic design codes lead to decrease the structural loads. This research to calculate the response modification factors (RMF) of conventional eccentric braced frames (EBFs). Since, the response modification factor depends on the ductility and over-strength, the static nonlinear study has been accomplished on building models including type three length of link beam, with 3,5,7 and 10 stories and with different brace arrangements (open chevron invert V and open diagonal bracing), Further, the linear dynamic and incremental nonlinear dynamic study was performed on building models under Indian conditions. The results indicated that the response modification factor for open diagonal eccentric braced frame was higher than the open chevron eccentric braced one. It is also found that the length of the link beam and the height of buildings have had larger effect on the response modification factors.
