Seismic Isolation Systems is the system used to reduce the effects of earthquake ground shaking on structure, their components and protect them from damaging. The system decouples the building or structure from the horizontal components of the ground motion by interposing structural elements with low horizontal stiffness between the structure and the foundation. This gives the structure a fundamental frequency that is much lower than both its fixed-base frequency and the predominant frequencies Mais
