Abstract

This paper proposes a new type of buckling-restrained braces with post-tensioned cables (PT-BRB). Such braces enable various hysteresis shapes between bilinear (ȕ=2.0) and flag-shaped (ȕ=1.0) behaviors. After a thorough numerical study for investigating the effect of post-yield stiffness (Į) and energy dissipation (ȕ) ratios, 1/3 scale specimens were tested for confirming expected hystereses. With the experimental data acquired, impact of the hysteresis on seismic response of various types of steel structures with PT-BRBs is sought. Seismic performances of structures equipped with PT-BRBs or conventional BRBs are compared.
