Özet

Although buckling-restrained braces (BRBs) have an excellent energy dissipation capacity, damage concentration and large residual deformation occur due to their low post-yield stiffness when BRBs are used in steel frames with pinned connections. To avoid these risks, PT.BRB (BRB with Post-Tensioned cables) has been proposed that provides/enhances self-centering force by externally attached post-tensioned cables. The hysteresis is mainly dependent on post-yield stiffness (a) and energy dissipation (6) ratios. In this paper, after studying parameters (a and 6) minimizing residual deformation, cyclic loading tests of PT-BRBs are carried out, and obtained results are compared with numerical model.
