Friction dampers are devices used to reduce vibrations and oscillations in structures, such as buildings and bridges. They work by converting kinetic energy from movement into heat through friction, which helps stabilize the structure during events like earthquakes or strong winds. These dampers are often installed in critical areas to enhance safety and performance. They can be made from various materials and come in different designs, including steel and rubber components. By absorbing energy, friction dampers play a vital role in engineering, ensuring that structures remain safe and functional under stress.
