A structure stabilization system for protecting structures from effects of seismic disturbances. Plural bases of a base isolation system support, through flexible suspension elements, corresponding, plural vertical support columns. Corresponding adjustment mechanisms on each base provide for adjusting all support elements to a common elevation. A gripper mechanism in each base is selectively, axially adjusting to establish substantially identical, effective free suspension lengths and common harmonic characteristics of all suspension elements. A releasable interlock subsystem interlocks the structure to the foundation to render it stable against minor forces, such as produced by wind, and automatically releases the structure to permit same to float in support by the base isolation system in response to forces exceeding a predetermined level. A damping subsystem comprises plural dampers connected in symmetrically located positions between the structure and the foundation and arranged, at a minimum, as oppositely disposed, mutually orthogonal pairs, the associated dampers of each pair being hydraulically interconnected and mechanically connected between the structure and its associated foundation in inverse relationship. |
