Self-resetting energy consumption support

Abstract

A self-resetting energy consumption support comprises an inner constraint tube, an outer constraint tube, a wide ear plate, an anti-shear rivet, lead sand, an outer constraint tube ear plate, a baffle, fixed end plates, a rope, a clamp and an anchor plate. At a plant, the wide ear plate, the anti-shear rivet and the inner constraint tube are welded and spliced at first; the outer constraint tube ear plate, the baffle and the outer constraint tube are welded and spliced; the inner constraint tube is disposed in the outer constraint tube; the outer constraint tube is then welded and connected; then, the rope of the self-resetting system is inserted into the inner constraint tube and then passes through openings of the fixed end plates; prestress is applied to tightly press the fixed end plates on two ends of the outer constraint tube; the rope is tensioned and anchored on the anchor plate by the clamp; and finally, the lead sand is poured in via a pouring hole so as to form a lead center, and then splicing is completed. According to the invention, welding and splicing are completed at the plant; friction effects of the anti-shear rivet and lead sand have significant energy consumption effects; the self-resetting ability is high; the industrial production efficiency is high, etc.

Description

technical field [0001] The invention relates to a self-resetting energy-consuming support, which belongs to the technical field of steel structure application. Background technique [0002] At present, the frame-support structure system is one of the most widely used structural systems in multi-story steel structures. As a relatively new type of building, the frame-bracing structure has excellent seismic performance, which is of great significance to our country's anti-seismic work. When an earthquake occurs, the steel support can bear most of the horizontal shear force and reduce the horizontal displacement of the overall structure. [0003] The traditional common central support is prone to lateral buckling under the action of horizontal earthquake, especially under the action of reciprocating horizontal earthquake, when the stress of the structure enters the elastic-plastic range, the shear capacity and lateral stiffness of the floor will drop sharply, and it is easy to ...

Problems solved by technology

[0003] The traditional common central support is prone to lateral buckling under the action of horizontal earthquake, especially under the action of reciprocating horizontal earthquake, when the stress of the structure enters the elastic-plastic range, the shear capacity and lateral stiffness of the floor will drop sharply, and it is easy to In the traditional eccentrically supported structural system, due to the large plastic deformation of the energy-dissipating beam section, it is extremely difficult to repair after the earthquake

The traditional buckling-resistant bracing member is an energy-dissipating shock-absorbing device for lateral force applied in multi-story structures. Under the action of moderate or large earthquakes, the buckling-resistant bracing member can fully yield the entire cross-section during tension and compression without The overall or local buckling failure of the supporting components changes the original energy dissipation mode through the plastic hinge at the beam end of the main structure to only the concentrated energy dissipation on the anti-buckling supporting parts, thereby better protecting the main structure; However, the residual deformation of buckling-resistant braces is relatively large, and the corresponding residual deformation of the overall structure is also relatively large, making post-earthquake repair difficult and costly

[0004] These traditional support members do not have self-resetting ability, so the post-earthquake repair is difficult, costly and takes a long time for normal use
