Viscoelastic dampers are devices used to reduce vibrations and control movement in structures, such as buildings and bridges. They work by converting kinetic energy from vibrations into heat through a viscoelastic material, which has both viscous and elastic properties. This helps to minimize the impact of forces like wind or earthquakes. These dampers are often installed in critical areas of a structure to enhance stability and safety. They are particularly effective in seismic design, where they help absorb and dissipate energy during an earthquake, protecting the integrity of the structure and its occupants.
