SEISMIC ISOLATION SYSTEMS

Abstract

IEEE Seismic isolation systems are engineering solutions designed to protect structures from the damaging effects of earthquakes by decoupling the building from ground motion. These systems reduce the seismic energy transmitted to the structure, enhancing safety and minimizing damage. Key types of seismic isolation systems include base isolation (using elastomeric bearings, sliding bearings, and hybrid systems), damping systems (such as viscous and friction dampers), shock absorption systems, and energy dissipation systems. These systems improve building stability, extend the lifespan of structures, and reduce repair costs. Seismic isolation is widely applied in high-rise buildings, bridges, critical infrastructure, and historical structures to ensure safety and operational continuity during earthquakes
