Problems solved by technology

However, the dampers that have been used in practical engineering have some limitations: viscoelastic dampers have poor fatigue resistance and are prone to aging; viscous dampers are prone to leakage; metal yield dampers are prone to large deformation and failure in strong earthquakes; The friction damper has constant frictional resistance and poor resetting
It is worth noting that the above-mentioned types of dampers are usually difficult to disassemble and assemble. Once installed, it is difficult to carry out daily maintenance and replacement of parts after the earthquake, which increases the economic cost and work complexity of energy dissipation and vibration reduction.

Description

technical field [0001] The invention belongs to the technical field of damping devices, and in particular relates to an assembled self-resetting variable frictional damping device. Background technique [0002] Under the action of an earthquake, the damage and collapse of buildings will lead to serious casualties and economic losses. How to effectively reduce the seismic response of building structures and improve the seismic performance of structures is one of the problems to be solved in civil engineering. In recent decades, scholars have carried out a large number of experiments and theoretical studies on various types of dampers with energy dissipation and vibration reduction functions. The control methods of the damper can be divided into passive control, active control and semi-active control. Passive control has attracted much attention from the engineering community because of its simple structure, low cost and no need for external energy support. It is currently a ...
