Problems solved by technology

[0004] The buckling-constrained brace can ensure that it yields without buckling under the action of earthquake force, which greatly increases the area of ​​its hysteresis curve and improves its energy dissipation capacity under the action of the earthquake. After the action, it will produce a large residual deformation, and the main body of the structure will also have a large residual deformation, which is not easy or even impossible to repair.

Abstract

The invention discloses an assembled self-resetting energy-consuming support device, which belongs to the field of civil engineering. The assembled self-resetting energy-dissipating support device includes a peripheral constraining unit, a self-resetting unit, an inner core connection unit and an internal energy-dissipating unit, and the peripheral constraining unit includes a first constraining plate, a second constraining plate, a bottom plate, and a channel steel constraining unit; The self-resetting unit includes a first limit baffle, a third limit baffle, a third small baffle, a second limit baffle, prestressed tendons, the prestressed tendons are fixed with anchors, and the inner core connection unit includes a core plate , the first small baffle, the second small baffle. The present invention can make full use of the existing dampers, so that most of the dampers can be assembled into self-resetting energy-dissipating supports through the self-resetting device.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to an assembled self-resetting energy-consuming support device. Background technique [0002] Disasters caused by earthquakes have been widely concerned by all walks of life, and the frame structure is a structural form that is widely used at this stage. In the frame structure, the absolute rigidity of the beam-column structure of the building itself is improved to resist earthquakes at first. However, this method is not only costly, but also the building will move sideways after the earthquake, and the beams and columns will also be damaged, resulting in high repair costs for the building. [0003] The frame-bracing system solves the problem of lateral stiffness of the frame system to a certain extent, but the support in the frame structure is difficult to withstand repeated earthquakes, resulting in damage and failure of the joints or the support itself. In addition, when a brac...
