A system for performing computing operations includes a rack that rests on a floor and a stabilization device coupled on the top of the rack. The stabilization device includes a mounting portion coupled to the rack, a ballast member, and one or more spring devices coupled between the ballast member and the mounting portion. The ballast member reduces displacement of the rack from seismic loads transmitted from the floor to the rack to mitigate effects of the seismic loads on the rack.
