Seismic isolation is a technique used in building design to protect structures from the effects of earthquakes. It involves placing flexible bearings or pads between a building's foundation and its superstructure. These isolators allow the building to move independently from ground motion, reducing the forces transmitted during an earthquake. This method helps to minimize damage to the structure and enhances safety for occupants. Seismic isolation systems can be found in various types of buildings, including hospitals, schools, and bridges, ensuring they remain functional after seismic events. This technology is crucial in earthquake-prone areas, where the risk of damage is significant.
