Abstract

The invention belongs to the technical field of the civil engineering energy dissipation and seismic mitigation, and discloses a self-resetting support structure. The self-resetting support structurecomprises an energy dissipation component and an elastic resetting component. The energy dissipation component comprises an anti-buckling support. The elastic resetting component comprises a first pushing-pulling rod, a second pushing-pulling rod, an elastic component, a first outer anchoring plate, a second outer anchoring plate, an inner sleeve and an outer sleeve. The beneficial effect is as follows: 1, the elastic component is parallelly connected with the anti-buckling support, so an axial force of the whole self-resetting support structure is the sum of a reset force of the elastic component and an axial force of the anti-buckling support, the self-resetting support structure is stable in mechanical property, and strong in deformability; and 2, the elastic component is connected withtwo outer anchoring plates, a prestressing force is adjustable through adjusting initial deformation of the elastic component, disadvantage phenomena, such as later loosening of the self-resetting support structure, can be solved, and later detaching and repairing are more convenient.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption in civil engineering, in particular to a self-resetting support structure. Background technique [0002] The energy input to a structure by an earthquake is related to the structure's self-weight and fundamental period. Energy dissipation and vibration reduction technology consumes part of the seismic energy originally consumed by structural components (such as beam-column nodes) by setting passive damping devices in the structure, which greatly reduces the deformation and damage of the structure. Passive energy dissipation shock absorption technology is currently considered the most effective, feasible and reliable shock absorption technology in the world. As a passive energy-dissipating device, the friction damper has a good application prospect because of its strong energy-dissipating capacity, the size of the load and its frequency has little effect on its perf...
