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...

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.
