base isolators

base isolators

[′bās ‚ī·sə¦lād·ərz]
(civil engineering)
Components placed within a building (not always at the base) which are relatively flexible in the lateral direction, yet can sustain the vertical load. When an earthquake causes ground motions, base isolators allow the structure to respond much more slowly than it would without them, resulting in lower seismic demand on the structure. Isolators may be laminated steel with high-quality rubber pads, sometimes incorporating lead or other energy-absorbing materials.

2, a catastrophic earthquake, the cathedral rides as a unit on rubber and steel base isolators, primarily supporting the walls, while Teflon-bearing sliders on flawless faces of stainless steel support the nave floor.
Ever-Level's new technology includes base isolators, a two-part system designed to separate a building from ground shock and movement during an earthquake.
As part of the facility's "earthquake-ready" status, the 950,000-squarefoot medical center is constructed with base isolators and hydraulic shock absorbers, allowing the building to move 22 inches in any direction should an earthquake occur.
According to Eloy Retamal, the project's structural engineer, the entire building rests on 28 base isolators (elastomeric bearings) that allow the building to move 16 inches in any horizontal direction.
The building modules can be trucked directly to the site with low-boy trailers and placed directly on to our proprietary Seismic Foundation Base Isolators.

Tim Algier, Architect and CEO of MC Endeavors reiterated that, "The Quake Guard Base Isolators connected and supporting our Lamisteel frames become one integrated building structure that will absorb the earthquake and wind vibrations.
The restoration would involve gutting the interior and earthquake retrofitting the structure with the potential use of base isolators to prevent the building from being damaged the way it was in the 1994 Northridge Earthquake.
Tim Algier, Architect and CEO of MC Endeavors stated that, "The Quake Guard base isolators are very economically designed and will play a key role in the foundation engineering for the reconstruction efforts to rebuild cities and communities within the earthquake ravaged countries of Haiti, Chile, New Zealand, China, and Japan.
