application field

Friction damper is a passive control device that utilizes sliding friction between solid contact surfaces to dissipate energy.

Main application areas

Seismic and Wind Resistance of Building Structures

Suitable for high-rise buildings, large-span structures, and industrial plants, effectively controlling the displacement and internal forces of structures under earthquake or strong wind conditions.

Especially suitable for the reinforcement and renovation of existing buildings, it can improve damping performance without significantly increasing structural stiffness.

Bridge Engineering

Used in bridge structures such as beam bridges, cable-stayed bridges, and suspension bridges to control displacement caused by earthquakes, vehicle loads, or wind-induced vibrations.

It can be used as a connecting beam device or a limiting device to adjust the response behavior of bridges during earthquakes.

Vibration Control of Equipment and Pipeline Systems

Widely used in key industrial settings such as power plants, petrochemical facilities, and nuclear power plants to protect important equipment and pipeline systems from earthquakes or operational vibrations.

Has good fatigue resistance and is suitable for long-term vibration environments.

Strengthening of historical buildings and protective structures

Due to its simple structure, flexible size, and ease of concealed installation, it is commonly used for seismic reinforcement of ancient buildings and commemorative structures, enhancing seismic resistance while maintaining the original appearance.

working principle

Friction dampers (CFD) consume input energy through frictional sliding between components, and are widely used in engineering due to their simple structure, stable performance, and high damping force. For structures with friction dampers, under normal load conditions, the friction dampers provide additional stiffness to the structure without slipping themselves; Under moderate to large earthquakes, friction dampers generate frictional sliding work to consume and absorb the energy input from the earthquake, providing additional damping to the structure and reducing its response.
