When two contacting objects move relative to each other, the friction force opposite to the sliding direction is generated on the contact surface to convert the vibration energy of the building into heat energy and dissipate it.

Features of Friction Dampers

High cost performance and small cross-section.

The sliding displacement is small.

Strong energy consumption capacity.

Simple connection method

Application of Friction Dampers

As one common types of friction dampers for buildings, these seismic friction dampers are mainly used in schools, hospitals, large public buildings, public places with high density of people, industrial plants, parking lots, bridges, municipal engineering and other fields.

As well as new construction projects, friction dampers in buildings are used for seismic reinforcement and the renovation of existing structures.
