A friction damper is a passive energy dissipation device widely used in structural engineering to enhance the seismic and dynamic performance of buildings and infrastructure. It operates on the principle of Coulomb friction, where mechanical energy is converted into heat through controlled sliding between friction surfaces. When a structure is subjected to external forces such as earthquakes or strong winds, the friction damper activates at a predefined load level and dissipates the induced energy, thereby reducing vibrations and limiting structural damage.

Friction dampers are valued for their simplicity, reliability, and cost-effectiveness, as they do not require external power or complex control systems. They can be easily integrated into new constructions or retrofitted into existing structures without significant architectural modifications. Additionally, their performance remains stable over repeated loading cycles, making them suitable for long-term applications.

With customizable design parameters such as slip load and friction materials, friction dampers can be tailored to meet specific project requirements, ensuring optimal structural safety, enhanced durability, and improved overall performance under dynamic loading conditions.
