Uses of buckling restrained braced frames (BRB) as seismic load resisting system have been developed in recent years. BRB is a proper alternative to the conventional bracing system due to its ductility and good performance. In order to reduce manufacturing cost and ease of handling of BRBs elements the idea of using reduced length BRB as a ductile braces has occurred. However, by increasing strains amplitude of these elements because of reduced length the occurrence probability of low cycle fatigue increase that prevent the expansion of this system. Therefore, in this study were trying to find a solution to get out of this problem by making change in the geometry of the bracing placement pattern and use the reduced length BRB in eccentric configuration like EBF system with the exception that here the BRB is the ductile element.
