Repair-free self-resetting friction energy-consuming support

Abstract

The invention relates to the technical field of frame and support structures, in particular to a repair-free self-resetting friction energy-consuming support. By the repair-free self-resetting friction energy-consuming support, earthquake inputting energy can be consumed by friction between a first friction plate and a second friction plate in a friction energy-consuming mechanism when an earthquake happens, earthquake response of a main body structure is reduced, after earthquake action, the support can recover to an initial state under the effect of a self-resetting mechanism, and residual deformation of the whole structure is reduced and even eliminated. Moreover, compared with the existing self-resetting support, the repair-free self-resetting friction energy-consuming support can still guarantee stable friction energy consumption under repeated reciprocating action, can still be used after the earthquake, and does not need to be repaired after the earthquake. In addition, the repair-free self-resetting friction energy-consuming support is simple in structure and convenient to mount; a construction technology is simplified greatly; and requirements of architectural industrialization are met.

Description

technical field [0001] The invention relates to the technical field of frame-support structures, in particular to a repair-free self-resetting frictional energy-dissipating support. Background technique [0002] At present, the frame-bracing structure system is one of the most widely used structural systems in high-rise steel structures. Under earthquake action, steel supports bear most of the horizontal shear force and reduce the horizontal displacement of the overall structure. However, in the traditional central support structure system, the general support is prone to overall and local buckling under the reciprocating action of tension and compression, resulting in its brittle fracture and finally seriously affecting the seismic performance of the overall structure. In the traditional eccentric support structure system, the energy-dissipating beam section The plastic deformation is large, and it is extremely difficult to repair after the earthquake. In order to solve th...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: the traditional self-resetting support needs to replace the whole support when it is repaired after the earthquake, the work is difficult and costly, and the structure is complex, the assembly process is cumbersome and it is not easy to control the accuracy, so it is necessary to provide a structure Simple, easy to assemble, repair-free self-resetting frictional energy-dissipating support that can be restored to its original state after a moderate or large earthquake, so that the support can return to normal performance without repair after the earthquake
