ABSTRACT:
A system for protecting a building or piece of equipment against the forces generated by an earthquake is characterized by one or more approximately horizontal interfaces having sliding means associated therewith which permit relative horizontal multi-directional sliding movement between the superstructure and the supporting substructure. Calibrated control means such as low-friction sliding means and/or adjustable friction clamps may be utilized to adjust the threshold horizontal force required to cause such relative movement. Biasing means such as spring members may be utilized to urge the superstructure towards its pre-earthquake alignment relative to the substructure. Other advantages are provided by substrate grid means that permits the ready adjustment of the friction force exerted by the low-friction sliding means, and by the concave configuration of the sliding interfaces. A method of installing such a system is disclosed.
