Abstract
The invention relates to a self-resetting buckling-restrained brace, comprising a central positioning plate and secondary buckling-restrained units located on the left and right sides; the secondary buckling-restrained units each comprise a connection node, a brace core component, an outer sleeve steel pipe, a sliding load-bearing plate, a fixed load-bearing plate, a stabilization steel bar, steel frame braces, a Belleville spring and friction plates; the brace core component, the sliding load-bearing plate and the stabilization steel bar are connected in order and slide into the outer sleeve steel pipe; the middle portion of the brace core component penetrates through the outer sleeve steel pipe, and the outer end of the brace core component is fixedly connected to the connection node; the fixed load-bearing plate, the steel frame braces and the central positioning plate are connected in order, and an inner end of the stabilization steel bar penetrates through the fixed load-bearing plate; the friction plates in contact with the stabilization steel bar are provided between the fixed load-bearing plate and the central positioning plate; and the compressed Belleville spring is sleev…
