Bending type damper with adjustable damping force

Abstract

The invention relates to the technical field of energy dissipation and shock absorption, and discloses a bending type damper with adjustable damping force. The bending type damper comprises a first flange plate, a second flange plate and basic bending energy dissipation elements, wherein an even number of first bolt holes are formed in the first flange plate and are symmetrically distributed about the circle center of the first flange plate; an even number of second bolt holes are formed in the second flange plate and are symmetrically distributed about the circle center of the second flange plate; the first flange plate and the second flange plate are oppositely arranged, and a gap is reserved between the first flange plate and the second flange plate; the first bolt holes correspond to the second bolt holes in a one-to-one manner; and one end of each basic bending energy dissipation element is detachably connected with the corresponding first bolt hole, and the other end of each basic bending energy dissipation element is detachably connected with the corresponding second bolt hole. The bending type damper has the beneficial effects that when the structure is reinforced or the anti-seismic and wind-resistant requirement is changed, the damping force can be adjusted by increasing or decreasing the number of the basic bending energy dissipation elements, the damping force of each energy dissipation element is adjusted through the number of energy dissipation steel sheets, and operation is simple and easy to conduct.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption, in particular to a curved damper with adjustable damping force. Background technique [0002] In order to improve the seismic performance of building structures and enhance the energy dissipation capacity of the structure itself, it is a common technical means to install additional energy dissipation devices. BRB energy-dissipating support, lead core damper, mild steel damper, etc. are more commonly used damper forms. According to different needs, we have developed many damper products such as velocity type, displacement type, bending type and shear type. Among them, the curved damper is widely used because it can dissipate energy under small displacement and has high ductility to dissipate a large amount of seismic energy.

AI Technical Summary

Problems solved by technology

In previous earthquake damages, due to the complicated connection structure measures, the damaged dampers are often inconvenient to replace; the damping force of general dampers is a fixed value, which cannot be adjusted according to the actual earthquake level and reinforcement structure requirements. The force cannot meet the energy consumption requirements, and the excessive damping force requires the structure to enter a large displacement to play a role, and it needs to be replaced as a whole to meet the requirements, resulting in a large mess
