Inward-outward double-bent soft steel transverse-wave vertical-bent buckle damper

Abstract

The invention discloses an inward-outward double-bent soft steel transverse-wave vertical-bent buckle damper. An upper base, a first connection plate, a first spring, a second connection plate, a wavysoft steel barrel, a third connection plate, a second spring, a fourth connection plate and a lower base are sequentially distributed from top to bottom, the first connection plate is fixed at the bottom of the upper base, one end of the first spring is connected with the bottom of the first connection plate while the other end of the same is connected with the upper portion of the second connection plate, the upper end of the wavy soft steel barrel is connected on the second connection plate in a sleeved manner while the lower end of the same is connected on the third connection plate in a sleeved manner, the upper end of the second spring is connected with the bottom of the third connection plate while the lower end of the same is fixed on the fourth connection plate which is fixed on the lower base, and wavy steel plates are distributed on the periphery of the wavy soft steel barrel circumferentially. The damper can realize staged energy-consuming damping.

Description

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

AI Technical Summary

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
