Base Isolation Systems – A State of the Art Review According to Their Mechanism [PDF]
Journal of Rehabilitation in Civil Engineering, 2020 Seismic isolation is a method to reduce the destructive effects of earthquakes on a structure in which the structure is separated from its foundation by devices called seismic isolators. As a result, the horizontal movements of the earthquake transmitted
