The traditional buckling-restrained brace is mainly composed of an internal core material, an external restraint member, a non-bonding expandable material and a non-bonding sliding interface, and is connected between adjacent floor slabs. When a strong earthquake occurs, the buckling-restrained brace buckles. The end connection of the existing buckling-restrained brace is generally welding or bolt connection. However, stress concentration is prone to occur at the end of the buckling-restrained brace during welding, and the welding part is prone to fracture during an earthquake, resulting in buckling failure. The bolt connection needs to drill holes in the buckling-restrained brace, and the processing precision is high and the installation is complex.
