a new repairable concentric brace with dual-performance

Due to considerable damages of the infrastructures caused by earthquakes and following high-cost reconstructions, the design and utilization of the repairable structures have been intensified recently.in designing the repairable structures, a serious concern is that most of the structural systems use only singleperformance fuse elements, and they, inevitably, are designed for the largest possible earthquakes. consequently, for moderate earthquakes, the considerable damages of other structural members are very likely (hosseini hashemi & alirezaei, 2015; hosseini hashemi & moaddab, 2017; zahrai & vosooq, 2013).
