ABSTRACT:
A system for protecting a building against the forces generated by an earthquake. The horizontal movement of the building superstructure relative to the foundation is adjustable to adapt its damping system to prevailing wind conditions. The superstructure moves horizontally along a system of movable plates provided at the interface between the superstructure and the foundation. Wind velocity reading devices placed on the exterior of the building provide signals to a transducer which adjusts a controller to vary a threshold force applied to the superstructure to determine the force required to initiate movement of the superstructure relative to the foundation. A sandwiched system of three levels of low friction plates beneath each column, interconnected by three levels of diaphragm linkages, restricts the movement of the columns and walls solely to a combination of orthogonal, rectilinear motion.
