AI Technical Summary
Technical Problem
Existing buckling-restrained braces require welding to attach anti-slip projections, which is time-consuming and challenging to set the length and shape of the projections correctly due to potential cross-sectional defects and strength requirements.
Method used
The core material is equipped with integrally molded projections that fit into grooves or are sandwiched between segmented stiffeners, eliminating the need for welding and allowing easy determination of the projection's length and shape.
Benefits of technology
This configuration simplifies the manufacturing process, reduces processing time, and ensures accurate setting of projection dimensions, enhancing the brace's seismic energy absorption and structural integrity.

Abstract
The present invention relates to a buckling-restrained brace having a core material equipped with protrusions for preventing shearing, and aims to provide a buckling-restrained brace that can overcome the challenges of attaching the protrusions to the core material by welding, and that allows for easy setting of the length, shape, and strength of the protrusions. [Solution] The core material 10 is made of a steel plate, and a pair of steel restraining members 30 are arranged to face a pair of wide surfaces 11 of the core material 10. A pair of stiffening members 40 are joined to both sides of the pair of restraining members 30 on the side of the core material 10 and extend in the longitudinal direction of the core material 10. A projection 14 that protrudes toward the stiffening member is provided on at least one of the pair of narrow surfaces 12 of the core material 10 as an integrally molded member of the core material 10, and the projection 14 fits into a groove 45 provided on at least one of the pair of stiffening members 40.
