BIB is composed of three main components : (1) main load carrying element, which carries axial force and dissipates energy, (2) lateral support system, which constraints loacl buckling and overall buckling deformation of the main load carrying element,(3) silding mechanism, which reduces trans- mission of axial forces form main load carrying eleme- nts to lateral support systems to keep lateral systems form being damageed. In this study were used, elastic stability theory and full - scale structural testing to explore : (1) overall buckling strength of BIBs , (2) hysteretic behavior of BIBs,(3) performance of new sliding mecha- nism. Test results shows that the hysteretic behavior of BIBs is stable and the strength of BIBs is well developed.
