Earthquake isolation (also called seismic isolation, seismic isolation or base isolation) is a system that protects the structure and all components inside the structure from the destructive effects of earthquakes by creating a layer between the structure and the ground, thanks to special devices (earthquake isolation devices) placed between the structure itself and its foundation. method. Earthquake isolators (also called earthquake isolation devices, seismic isolators or base isolation devices) are placed in the structures, one for each column and more than one under the curtain walls, and the superstructure is separated from the foundation and the ground.
