Problems solved by technology

However, the existing friction energy dissipators are mainly plate-type structures, which have the disadvantages of uneven force on the fastening surface, easy relaxation, and unstable binding force. When earthquake occurs, it cannot provide greater stiffness and damping to prevent the structure from entering an inelastic state

Abstract

The invention provides a friction damper. The friction damper comprises a cylinder body and a force guiding device, wherein a cavity is formed in the cylinder body, the force guiding device is arranged in the cylinder body, damping force exists between the part, located in the cavity, of the force guiding device and the cylinder body, the part, extending out of the cylinder body, of the force guiding device and the cylinder body are connected with other assemblies respectively, and when the force guiding device moves under impact force, the larger the movement displacement is, the larger the damping force between the force guiding device and the cylinder body is. According to the friction damper, damping force is increased along with increase of displacement, so that certain rigidity and energy dissipation capacity necessary for shock absorption are provided for a structure, and the energy dissipation capacity is enhanced along with increase of the displacement of the structure; and the displacement response of a building structure can be effectively controlled during a large earthquake, the horizontal rigidity and damping of the structure are both increased, and the stability and safety of the structure can be greatly enhanced.

Description

technical field [0001] The invention relates to a friction damper, in particular to a variable damping energy-consuming shock-absorbing friction damper, which belongs to the technical field of construction engineering. Background technique [0002] In recent years, earthquakes have occurred frequently, and the seismic technology of buildings has gradually attracted the attention of relevant government departments and the public; traditional seismic technologies are mainly divided into two categories: shock absorption technology and seismic isolation technology. Shear walls, connecting joints or connecting members) are provided with energy dissipation (damping) devices (or elements). Before the main body enters the inelastic state, the device (or element) first enters the energy dissipation working state, and the device generates friction, bending (or shear, torsion) elastic-plastic (or viscoelastic) hysteretic deformation to dissipate energy or absorb earthquakes Energy inp...
