In this paper, after taking a lookat the importance of the degree of behavior factor and its application for structures, its objective and efiective parameters upon its quantity have subsequently been investigated. The quality of achieving this factor from one of the common methods (the method developed by Freeman) has been discussed. Then, parameters used in this paper for calculating the behavior factor have been defined and the behavior factor for twodimensional V/A-shape steel braced coaxial structures have been obtained by allocating the restraint of the beam to the column and its base plate, in addition to considering strain hardening from Young's modulus as comparison. Finally, the results are reviewed.
