Seismic Retrofitting
Seismic base isolation is a relatively new seismic retrofitting technique that enhances a structure’s flexibility to withstand lateral forces during an earthquake. When placed under a load-bearing column of a bridge or building, base isolators function like large “motor mounts.” During a seismic event, these isolators absorb the impact, significantly reducing the seismic forces transmitted through the building.
