Product Description

Seismic Isolation Bearings for Building Construction

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.

How have isolation systems performed in Earthquakes?
The USC Hospital was isolated using Dynamic Isolation Systems isolators. The building remained operational throughout the 1994 Northridge Earthquake. There was no damage to the USC Hospital. In contrast the Los Angeles County Medical Center located less than a mile away suffered $400 million of damage and was not operational after the earthquake.
The Stanford Linear Accelerator in Palo Alto California was unscathed by the 1989 Loma Prieta earthquake. Elsewhere on campus damage was reported to be approximately $160 million.
The Eel River Bridge in Humboldt County, California, was isolated using DIS isolators in 1988. It experienced accelerations of 0.55g in the 1992 Petrolia Earthquake. The bridge displaced 9 inches laterally and sustained no damage.
