Embodiment Construction

[0035] The following is attached figure 1 to attach Figure 11 The present invention is further described in detail with specific examples.

[0036] The existing buckling-constrained support includes a support rod, a sleeve surrounding the outside of the support rod, and mortar poured between the sleeve and the support rod. The two ends of the supporting rods are connected with the building structure, as the main force-bearing parts of the buckling-restrained bracing, and the mortar set in the sleeve forms the restraint on the lateral (or transverse) buckling of the supporting rods. In addition, the buckling section of the supporting rod is also painted with non-bonded material, and the mortar contacts with the non-bonded material and frictionally dissipates energy. Although this type of buckling-constrained brace has excellent support stiffness and energy dissipation performance, it is difficult to self-reset after the support rod is deformed, and the recovery performance n...

Abstract

The invention relates to the technical field of structural energy dissipation and shock absorption, and provides a supporting device and a lateral force resisting component. The supporting device comprises a core plate, a restraining sleeve, a filling piece and a self-resetting energy dissipation piece. A first end plate and a second end plate are arranged at the two opposite ends of the core plate correspondingly. The core plate is sleeved with the constraint sleeve; the self-resetting energy dissipation piece and the filling piece are arranged between the core plate and the restraining sleeve, one end of the self-resetting energy dissipation piece is connected with the first end plate, the other end of the self-resetting energy dissipation piece is connected with the restraining sleeve, the self-resetting energy dissipation piece is further connected with the core plate, and the self-resetting energy dissipation piece comprises at least one section of shape memory material piece. And by utilizing the self-resetting performance of the self-resetting energy consumption piece, self-resetting of the core plate after deformation is achieved, and the resetting performance of the supporting device is improved. And meanwhile, the self-resetting energy dissipation piece can also improve the energy dissipation capacity of the supporting device.

Description

technical field [0001] The invention belongs to the technical field of structural energy dissipation and shock absorption, and in particular relates to a support device and a lateral force-resistant component. Background technique [0002] Buckling-restrained bracing is a structural lateral force-resisting member with simple installation and excellent performance. The conventional buckling restrained support is based on the ordinary support, and the outer side of the support bar is surrounded by a sleeve, and mortar is poured between the sleeve and the support bar to form a constraint on the lateral buckling of the support bar, which avoids the failure of the compression bar. Stabilization effect, so as to give full play to the material strength and stiffness of the supporting rods, and provide sufficient supporting stiffness in the elastic stage. [0003] Although the buckling-restrained brace has excellent brace stiffness and energy dissipation performance, its recovery p...
