Anchor Raised Computer Floors

Raised floors that support computer equipment are found in many buildings. These floors and the equipment they support can be damaged or destroyed due to inadequate anchorage to the structural floor.  Raised computer floors may collapse from earthquake forces. To reduce the risk for this type of damage, anchor the pedestals that support the raised flooring to the building’s floor and secure the pedestals to the wall. 

Effectiveness:

  • Somewhat to very effective.

 

 

NOTE:  None of the mitigation measures in these Handbooks should be considered ‘pre-approved’ or otherwise automatically eligible for FEMA funding. Only FEMA staff can determine eligibility, once they have determined that an applicant is eligible and they have reviewed a project proposal.
