Main Frame Installation Technique in Seismically Active Locations

      Disclosed is a technique to attach computer frames to floors in
seismically active locations to prevent damage from occurring to
frames when seismic activity occurs.

      In certain cases, personnel safety is the overriding factor,
with the computer operation being the secondary concern.  In such
cases, rigid restraints can be obtained using steel cables.  Being
highly flexible, steel cables provide two degrees of freedom movement
and permit the decoupling of seismic energy between the horizontally
shifting floor and the computer frame.

      Referring to Figure 1, computer frame 1 is shown resting on
raised floor 2, and firmly attached to subfloor 3 through springs 4.
The spring constant of springs 2 is calculated to allow dampening of
sudden movements of subfloor 3 to computer frame 1 and will permit
uninterrupted operation of computer frame.
