Overlapping self-centering frictional energy-dissipating brace

Abstract

The invention discloses an overlapping self-centering frictional energy-dissipating brace. The overlapping self-centering frictional energy-dissipating brace comprises an inner rectangular sleeve, an outer rectangular sleeve, a frictional energy-dissipating component, a first end plate, a second end plate and a pre-tension rod, wherein the frictional energy-dissipating component connects an inner sleeve bottom plate with an outer sleeve bottom plate, the first end plate is arranged in the inner sleeve, the second end plate is arranged in the outer sleeve, the pre-tension rod is arranged in the inner sleeve, and two ends of the pre-tension rod are anchored to the first end plate and the second end plate respectively. One part of the inner sleeve is inserted into the outer sleeve and overlaps with the outer sleeve, one end, inserted into the outer sleeve, of the inner sleeve contacts with the second end plate, and the first end plate contacts with one end of the outer sleeve. A top plate and the bottom plate at the non-overlapping end of the inner sleeve are connected with first connecting plates respectively, a top plate and the bottom plate at the non-overlapping end of the outer sleeve are connected with second connecting plates respectively, the first end plate contacts with inner sleeve push plates through a first end plate rubber pad, and the second end plate contacts with the inner sleeve push plates through a second end plate rubber pad.

Description

technical field [0001] The invention belongs to the field of civil engineering, and relates to a lap joint type self-centering friction energy consumption support for reducing earthquake disasters of engineering structures. Background technique [0002] Earthquakes bring extremely serious disasters to human beings. The traditional seismic design adopts the ductility design method, that is, under the action of an earthquake, through the early yield and failure of some structural components, but the overall function will not be lost, relying on the plastic deformation of the components to dissipate most of the seismic energy, so as to achieve The purpose of ensuring the safety of the main structure. [0003] Frictional energy-dissipating support is an energy-dissipating member that converts kinetic energy into heat energy through sliding friction to dissipate seismic energy. Due to its strong energy dissipation capacity, good shock absorption effect, and easy replacement aft...
