Web holes, there is provided the buckling restrained brace of rigidity and damping can the distortion of control structure under each level geological process effectively simultaneously, because under each level geological process, this support all can provide additional damping for structure, the effective seismic energy dissipating input structure, reduce the earthquake load effects of structure, thus effectively ensure that the safety of agent structure component.
Summary of the invention
The utility model provides a kind of buckling restrained brace providing rigidity and damping, can not simultaneously for structure provides the problem of additional stiffness and additional damping for the traditional buckling restrained brace of solution.
The technical solution of the utility model is: a kind of buckling restrained brace providing rigidity and damping, comprises core mandrel power unit 1, end 2, core damping unit 3, inserts 4, clearance layer 5, steel sleeve 6, connects changeover portion 7, adhesive-less layer 8; Wherein core mandrel power unit 1, core damping unit 3 form core cell, end 2 is connected with structural element node, steel sleeve 6 is filled inserts 4 and is formed constraint component, core cell surface arranges non-cohesive material and forms adhesive-less layer 8 and overcoat Constrained parts, being clearance layer 5 between adhesive-less layer 8 and constraint component, surrendering section connection for being connected changeover portion 7 with constraint.
Described core mandrel power unit 1 is the edge of a wing of i iron or H profile steel; Core damping unit 3 is perforate on i iron or H profile steel web.
The connected mode of described end 2 and structural element node for being articulated and connected, bolt is connected or is welded to connect.
Described inserts 4 is concrete or mortar.
Described steel sleeve 6 section form is rectangle, square or circular.
Described adhesive-less layer material is rubber, polyethylene, silica gel or latex.
Clearance distance between described adhesive-less layer 8 and constraint component inwall is 1 ~ 2mm.
Wherein, on described web, the number of openings, hole shape, opening diameter, perforate spacing regulate according to the performance requirement of buckling restrained brace.
The beneficial effects of the utility model are: no matter be all simultaneously for structure provides rigidity and damping, effectively can reduce the earthquake response of structure, be applicable to newly-built and stabilization works under frequently occurred earthquake, earthquake of setting up defences, rarely occurred earthquake effect.
