Abstract

The invention discloses a stepped viscous-friction damper, which comprises a top plate and a bottom plate; a first end plate and a second end plate are vertically spaced between the top plate and the bottom plate; one end of the first friction assembly is connected to the first end plate Fixed connection, the other end of the first friction component is cross-fitted with one end of the second friction component, and is fixedly connected by fasteners; the other end of the second friction component is fixedly connected with the second end plate; the viscous component is set at the Between the first friction component and the second friction component, one end of the viscous component is set through the first end plate, and the other end is set through the second end plate; in the present invention, under a small load, the viscous component plays an energy-dissipating role, and can realize Repeated use will play a role in the entire life of the structure; under heavy loads, the friction components and viscous components can dissipate together, effectively improving the energy dissipation effect of the damper; under different earthquake energies, the energy can be realized step by step Consumption, to achieve the purpose of shock absorption, buffering and energy dissipation, to ensure the safety of the structure.

Description

technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing technology of civil engineering, and in particular relates to a stepwise viscous-friction damper. Background technique [0002] At present, the energy dissipation mechanism of the friction damper in the friction zone is that when the external force between the friction plates does not exceed its sliding friction force, the friction zone can be regarded as a rigid body, and the elastic stiffness of the friction zone is very large; when the external force reaches the sliding friction force When the load is high, the seismic energy is dissipated through the friction and plastic deformation between the friction plates; but for small earthquakes, the fatigue performance of the friction damper is poor, and repeated loads always cause static friction between the friction plates. The loss of the friction plate is also irreversible, so that the energy dissipation capacity of the friction zon...
