Test Study of Novel Buckling Restrained Brace

This article introduces a novel buckling restrained brace (BRB) whose core members are restrained by transverse restraints which consists of two lines of parallel square tubes at both sides of the core member. Three different types of BRB are cyclically loaded in the investigation, using different restraining mode and steel types for the core members. Results of the experiment indicate that the transverse rib restraining mode is able to achieve expected effects. BRB specimens with LYP160 core member exhibit relatively better hysteresis performance than specimens with Q235 core member.
