The following detailed description of the present application is given for the purpose of enabling those skilled in the art to better understand the technical solutions of the present application, and the description in this section is only exemplary and explanatory, and should not be taken as limiting the scope of the present application in any way.
Referring to fig. 1 to 3, the present embodiment provides a novel buckling restrained brace, which includes a damping assembly and a support rod 100; the damping assembly includes a damping mass 200; the damping block 200 is positioned between the two steel plates 210, the two steel plates 210 are attached, and corresponding mounting grooves are formed corresponding to the damping block 200; when the two steel plates 210 are dislocated relatively, the built-in damping block 200 is plastically deformed due to the dislocation to dissipate the seismic energy.
In a preferred embodiment, the damping block 200 is a lead block made of lead, the lead block has dynamic recrystallization performance, can be circularly deformed for thousands of times within the designed deformation range without degradation, and has stable working performance and mechanical performance. The reciprocating load energy consumption of the frame can be realized.
In a preferred embodiment, the two steel plates 210 are connected by high-strength bolts; the steel plate 210 is provided with corresponding mounting through holes corresponding to the high-strength bolts. The two steel plates 210 are connected by high-strength bolts, and the friction force is generated during the position dislocation to dissipate the seismic energy.
In a preferred embodiment, the sides of the two steel plates 210 away from each other are further provided with node plates 220; the gusset plate 220 is vertically installed on the steel plate 210 at the middle of the steel plate 210 for installing the support pole 100.

When the supporting rod 100 bears the acting force of a small earthquake, the rotation cannot be generated due to the existence of the lead core steel rod 110, which is equivalent to a fixed connection and is more beneficial to bearing earthquake force. When bearing the action force of a large earthquake, the leaded core rod 110 is deformed due to the shearing force, so as to achieve the functions of dissipating energy and increasing the structural damping.
