Seismic isolators are devices designed to protect buildings and structures from the damaging effects of earthquakes. They work by allowing the building to move independently from the ground motion, reducing the forces transmitted to the structure. This helps to minimize damage during seismic events. These isolators can be made from various materials, including rubber and steel, and are often placed between the foundation and the building. By absorbing and dissipating energy, seismic isolators enhance the safety and resilience of structures, making them crucial in earthquake-prone areas, such as California and Japan.
