Problems solved by technology

[0004] The purpose of the present invention is to provide a self-resetting anti-buckling support structure based on disc springs for the technical defect that the existing self-resetting anti-buckling support structure can only be used for earthquake resistance of moderate or large earthquakes, and cannot be used for small-magnitude earthquake resistance of concrete buildings. Support, under a small displacement, that is, when the main structure is in an elastic state under the action of a small earthquake, it can dissipate energy through the friction between the discs and between the discs and the middle partition

Abstract

The invention discloses a self-resetting anti-bent support based on a belleville spring. Under small displacement, namely under the small shocking effect, when a main body structure is in an elastic state, energy can be consumed through friction among all discs and between the discs and intermediate clapboards. In addition, self-resetting after the self-resetting anti-bent support is shocked can be achieved, residual deformation of a structure is reduced, and after being shocked, the self-resetting anti-bent support can continuously work after appropriate maintenance, and an original supporting component does not need to be replaced.

Description

technical field [0001] The invention belongs to the field of anti-shock technology for buildings, and in particular relates to a self-resetting anti-buckling support based on disc springs. Background technique [0002] The anti-buckling brace is an energy-dissipating shock-absorbing device applied to the lateral force system of multi-story buildings or the seismic reinforcement of existing buildings. Under the action of a moderate earthquake or a large earthquake, the anti-buckling brace can achieve full-section yield without the appearance of the brace damage, so that the structural damage model is changed from the plastic hinge at the beam end to the energy-dissipative damage only on the anti-buckling support, so as to protect the main structure. The buckling-resistant bracing member has a clear force transmission mechanism, excellent performance, easy control of the damage location, and easy replacement, and has passed the test of a series of destructive earthquakes.
