Description

Technical field

[0001] The invention relates to the technical field of energy consumption and shock absorption control in building structures, in particular to a variable friction viscous fluid hybrid damper. Background technique

[0002] The damper is also called a damping device, which can provide movement resistance and reduce movement energy. It is widely used in fields such as high-rise buildings, bridges, and structural seismic reconstruction. At present, the dampers in the field of energy dissipation control technology can be roughly divided into two categories, one is displacement-dependent dampers represented by friction dampers; the other is velocity-dependent dampers represented by viscous fluid dampers Device. The friction damper has the characteristics of long deformation capacity and stable energy consumption, but its damping force is relatively fixed. However, the viscous fluid damper has mass loss due to the viscous fluid during long-term use, so the energy con...
