LRB Seismic Isolation Bearings
Seismic isolation provides superior performance compared to a traditional structural design. It reduces the forces and displacements in the structure by up to 75%. The isolation system accomplishes this by deforming laterally during the earthquake. After the earthquake this results in a functional structure with little or no damage.
What type of structures are isolation candidates?
- Hospitals, Bridges and Emergency Centers that require operation during and immediately
after an earthquake.
- Structures with valuable contents or operations such as data centers, communmications
facilities, high-tech manufacturing facilities and museums.
- Buildings with high occupancy such as low to medium-rise residences and office buildings.
- Historical Buildings
How does isolation provide cost savings?
In bridges, the foundation design is based on elastic forces. Isolation reduces elastic forces by up to 75%; this translates into direct cost savings in the foundation.
In buildings, Isolation provides cost savings over the life of the structure.
An isolated building will be essentially undamaged in an earthquake. By comparison a conventional building’s structure and contents will be damaged. The occupants will also experience interruption of their businesses sometimes for weeks or even months.
