Shape memory alloys (SMAs) are novel materials with great potential to enhance the performance of civil structures. SMAs have found applications in structural engineering due to their re-centering, high damping capacity, durability and fatigue resistance. Aforementioned characteristics of SMAs rely on two unique properties: shape memory effect (SME) and superelasticity. The results of investigations that carried out on SMA braced frames represent the functionality and viable performance of this bracing system. in this paper, SMA wire braces as seismic resisting members that installed diagonally in the frame structure is utilized and the behavior factor (R) and its components including ductility reduction factor and overstrength factor were evaluated by performing pushover analysis on models. The models are frames with different heights and share of braces. Finally, according to the response curves of pushover analysis the behavior factor (R) proposed for this type of bracing system.
