Self-resetting buckling-restrained brace device with replaceable energy consumption section

Abstract

The invention provides a self-resetting buckling-restrained brace device with a replaceable energy consumption section, the self-resetting buckling-restrained brace device with the replaceable energy consumption section comprises elastic brace sections and a buckling energy consumption section, the buckling energy consumption section is arranged in the middle, and the elastic brace sections at the two ends of the buckling energy consumption section are symmetrical components. Under the action of medium and large earthquakes, the function of a shock absorption damper is achieved, energy input into the structure is dissipated through deformation and damage of the supporting component, the component can be monitored after the earthquakes, and energy dissipation soft steel can be replaced only by dismantling bolts of the buckling energy dissipation section.

Description

technical field [0001] The invention belongs to the technical field of energy dissipation and shock absorption in civil engineering, in particular to a self-resetting anti-buckling support device with a replaceable energy dissipation section. Background technique [0002] The anti-buckling support is composed of inner core member and peripheral constraining member. The inner core member bears axial pressure, and the outer member constrains the lateral displacement of the inner core member, so that its full section yields under the action of axial pressure. It can not only provide lateral stiffness and strength for the main structure under small earthquakes, but also use its own plastic deformation to consume seismic energy during major earthquakes, reducing or even avoiding structural damage, so it has been widely used in engineering. However, the biggest disadvantage of this component is that it deforms a lot during strong earthquakes, and it cannot automatically return to ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims to solve the problem that the current anti-buckling support needs to be completely replaced and cannot be monitored during post-earthquake repairs, thereby providing a self-resetting anti-buckling support device with replaceable energy-consuming sections, which does not need to be replaced during post-earthquake repairs. Requires complete replacement, self-returns to original position after yielding, and allows internal monitoring
