Problems solved by technology

[0003] The energy-dissipative buckling restraint support device in the prior art changes its position due to the extrusion of the external restraint component, which causes the external restraint component to be unable to control the deformation of the energy-dissipative core material inside it, thereby prompting excessive deformation of the energy-dissipative core material. The energy-dissipating core material after excessive deformation cannot recover the deformation amount again, that is, the energy-dissipating core after excessive deformation no longer has the effect of seismic energy dissipation

Abstract

The invention relates to the technical field of earthquake resistance of building structure engineering, in particular to an energy dissipation buckling restraining brace device. The device comprises an external restraining assembly and an energy consumption core material limited in the external restraining assembly, the energy consumption core material is used for being connected with a building component, the external restraining assembly comprises restraining pieces spliced in sequence, and the adjacent restraining pieces are spliced and fixed through positioning pieces. The positioning pieces are used for fixing the positions of the restraining pieces so as to limit the size of an area defined by the restraining pieces. The energy consumption core material is limited in the area defined by all the restraining pieces. According to the device, positioning assemblies are arranged between the restraining pieces, and the relative positions of the restraining pieces can be fixed from all directions so that the size of a cavity formed by the restraining pieces cannot be changed even if the restraining pieces are extruded by the energy consumption core material. Therefore, the deformation amount of the energy consumption core material in the cavity is controlled within the range of the recoverable deformation amount, and the energy consumption core material is prevented from being broken due to excessive deformation.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of building structure engineering, in particular to an energy consumption buckling restraint support device. Background technique [0002] Buckling-restrained bracing is an important structural lateral force-resistant component and energy-dissipating component. In recent years, it has been widely used in the construction field of our country. It consumes the seismic input energy through the yield hysteresis of the metal, thereby slowing down the damage of the main structure. The buckling-restrained brace is composed of connecting sections, energy-dissipating sections, constrained components, and unbonded materials. Under earthquake action, the core stress-bearing parts of the buckling-constrained brace are effectively constrained by peripheral restraint components to avoid overall or local instability. Energy can be dissipated through tensile and compressive yielding, so that the buckling-c...
