ABSTRACT:
A stabilization system protects a structure, comprising at least a slab and having a foundation formed in the earth, from the effects of seismic disturbances. Pendulum support elements, secured at upper ends to respective support columns affixed to the foundation and at lower ends to support positions of the slab, support the slab while permitting limited relative movement between the slab and the support columns in the event of a seismic disturbance. A damping system connects the slab to the foundation to impede action of forces tending to produce relative rotation between the slab and the foundation and to provide damped control of relative linear displacements therebetween. A level monitoring system monitors the respective levels of monitoring positions displaced about the slab and detects differential changes in the levels at the monitoring positions, the rods being adjustable to correct for such differential changes and thereby to reestablish a common level condition at all monitoring positions.
