The novel adjustable double-step yield type buckling restrained brace consists of a main core plate and an auxiliary core plate, wherein the auxiliary core plate is welded with the joint of a flange, and the other end of the auxiliary core plate is connected with a sleeve through a bolt; in the process of tension pressure, the auxiliary core plates firstly enter the yielding state to perform energy dissipation and shock absorption, and the main core plates enter the yielding state to perform energy dissipation and shock absorption, so that different anti-seismic requirements can be met by adjusting the number of the auxiliary core plates, and the BRB has better anti-seismic performance compared with the traditional BRB.
Description
Technical Field
The utility model relates to the field of structural seismic resistance, in particular to a novel adjustable double-step yield type buckling restrained brace.
Background
The buckling restrained brace is also called as an anti-buckling brace or BRB. The BRB support is characterized in that a sleeve is arranged outside the support to restrain the support from buckling under pressure to form a buckling restrained support, only a core plate of the buckling restrained support is connected with other components, all the load borne by the core plate is borne by the core plate, and only the core plate is restrained from buckling under pressure by an outer sleeve and a filling material, so that the core plate can be buckled under tension and compression.
The buckling restrained brace has the advantages of high bearing capacity under pressure, good ductility and hysteretic performance, protection of a main body structure (a fuse is acted under the action of a large earthquake, and the main body structure is not yielded or seriously damaged under the action of the large earthquake), reduction of internal force of adjacent components and the like, and is widely used in earthquake-resistant constructions.
The traditional BRB only enters yielding from the main core plate under tension and compression, and the earthquake-resistant performance is poor.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects of the prior art, the utility model provides a novel adjustable double-step yield type buckling restrained brace, and solves the problem that the traditional BRB is poor in anti-seismic performance because the traditional BRB only enters yield under tension and compression by a main core plate.
In order to achieve the purpose, the utility model is realized by the following technical scheme: the utility model provides a novel adjustable two-step yield type bucking restraint is supported, includes the sleeve, and telescopic tip is equipped with the flange, is equipped with main core in the sleeve, telescopic tip equidistance is fixed with vice core.
Further, the novel adjustable double-step yielding type buckling restrained brace is further limited, wherein lifting lugs are welded on the surface of the sleeve.
Further limited, the novel adjustable double-step yielding type buckling restrained brace is characterized in that the secondary core plate is arranged at one end or two ends of the sleeve.
Further defined, the novel adjustable double-step yielding type buckling restrained brace is characterized in that one end of the secondary core plate is welded with the flange.
Further, the novel adjustable double-step yielding type buckling restrained brace is further limited, wherein a bolt hole is formed in the other end of the secondary core plate, and the bolt hole is connected with a mounting hole formed in the sleeve through a bolt.
Further defined, the novel adjustable double-step yielding type buckling restrained brace is characterized in that the cross section of the sleeve is rectangular or circular.
The utility model has the following beneficial effects: the novel adjustable double-step yield type buckling restrained brace consists of a main core plate and an auxiliary core plate, wherein the auxiliary core plate is welded with the joint of a flange, and the other end of the auxiliary core plate is connected with a sleeve through a bolt; in the process of tension pressure, the auxiliary core plates firstly enter the yielding state to perform energy dissipation and shock absorption, and the main core plates enter the yielding state to perform energy dissipation and shock absorption, so that different anti-seismic requirements can be met by adjusting the number of the auxiliary core plates, and the BRB has better anti-seismic performance compared with the traditional BRB.
