How Safe Do You Want Your Datacenter To Be

Bergvik Seismic Bracing Frames

In studies of earthquakes between 2000-2013, it has been shown that the vertical ground motion has created significant damage to nonstructural components in buildings. In mission critical Data Centers, Electrical and Telecom environments, raised floors are commonly used and will not amplify the vertical ground motions.


If a system is sensitive to shaking, it is likely to be sensitive in all three orthogonal directions. A lot of people are presently investing in lateral base isolation systems and will be shocked at the damage due to the vertical ground motions.


The Bergvik design does not depend on any support from a raised floor, but is instead securely anchored directly from the equipment Rack or Cabinet down to the concrete sub floor with Hilti seismic anchors.
