An internal and external double-bending soft steel transverse wave vertical bending buckle damper

Abstract

The invention discloses an internally and externally double-bent soft steel shear wave vertically bending buckle damper, comprising an upper base, a first connecting plate, a first spring, a second connecting plate, a corrugated mild steel cylinder, a third connecting plate, a The second spring, the fourth connecting plate and the lower base are distributed sequentially from top to bottom, and the first connecting plate is fixed on the bottom of the upper base, one end of the first spring is connected with the bottom of the first connecting plate, the other end of the first spring Connected with the upper part of the second connecting plate, the upper end of the corrugated mild steel cylinder is sleeved on the second connecting plate, the lower end of the corrugated mild steel cylinder is sleeved on the third connecting plate, and the upper end of the second spring is connected to the third connecting plate. The bottoms of the connecting plates are connected, the lower end of the second spring is fixed on the fourth connecting plate, and the fourth connecting plate is fixed on the lower base. The corrugated steel plates are distributed on the outer periphery of the corrugated mild steel cylinder along the circumferential direction. The damper can Energy consumption shock absorption is carried out in stages.

Description

technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing civil engineering, and relates to a buckle damper with internal and external double-bending mild steel transverse waves and vertical bending buckles. Background technique [0002] Metal energy dissipation damper is an energy dissipation device that can resist horizontal or vertical action in buildings. Metal energy dissipation damper can use different forms of plastic hysteretic deformation of metal to dissipate energy. Because it absorbs a large amount of energy during elastic-plastic hysteretic deformation, it is used to manufacture energy-dissipating shock absorbers of various types and configurations. From the force form, it can be divided into shear yield type, axial yield type, bending yield type and torsional yield type damper. Compared with other types of dampers such as hysteresis liquid type and friction type, metal dampers have the advantages of convenient processing, st...

Problems solved by technology

However, shortly after the main shock, it is often accompanied by large aftershocks and lasts for a long time. The traditional damper cannot achieve the expected energy consumption and shock absorption effect. Seriously, it is likely to affect the seismic performance of the structure and the overall safety performance of the structure. Therefore, the research and development New staged energy-dissipating dampers are a priority
