PERFORMANCE TEST AND ANALYSIS STUDY ON BUCKLING-RESTRAINED BRACE WITH ANGLE MEMBERS

Abstract

This research proposed an additional strengthening of the brace made of angles, and vibration control performance was verified in cyclic loading test. A joint of angle-buckling restrained brace（angle-BRB） has a cross-sectional component with combining the two angles inserted a gusset. Then, the geometric symmetry section of angle-BRB prevented an eccentricity bender effect. After obtaining these static experimental results, the energy absorption capacity as a vibration control member was performed in the hybrid response test.
