Abstract: A part of a building structure called the “elevated building foundation” to shield the building structure against 3D components of destructive earthquakes, comprising a massive horizontal plate (1) raised above the level of the ground and underpinned by multiple abutments (2); those abutments (2) are resting on individual footings at the level of the ground (3); the top surface of plate (1) is bearing a protected building superstructure (4).

Abstract: A manufacture called “earthquake protector” to shield a building structure against destructive earthquakes as well as to secure its stability under strong winds, comprising two ring-shaped segmented slide tracks containing plurality of freely revolving rollers made of hard material, said rollers in each track stretched parallel to one another, said tracks positioned above each other with their axes of rotational sliding being set horizontal and mutually orthogonal, said tracks comprising three properly configured race pads, namely: a lower pad resting on the building footing, an intermediate pad, and an upper pad supporting the building superstructure; top surface of the lower pad and bottom surface of the intermediate pad encompassing a lower track; top surface of the intermediate pad and bottom surface of the top pad encompassing an upper track; said pads being able to slide mutually along their tracks; a column stub underpinning and framed into the building superstructure, said column stab having its lower

Abstract: A manufacture to protect a building from destructive explosions, having a number of sliding connectors, each connector comprises a massive housing rigidly coupled to a structural frame of the protected building and a low friction slider fixed to a wall panel. Each housing comprises a grooved track for the slider, and each track is sagged down to its middle where the slider rests under normal conditions. When the blast occurs, the wall panel does not transfer its impulse to the building frame immidiately but, remaining parallel to its initial position, distributes this transferal during a sequence of pendulum type excursions thus considerably mitigating the explosion impact on vital structural elements of the building.

Abstract: A manufacture to protect a structure from destructive earthquakes, having a number of slip joints, each joint comprises a consumable-while-sliding vertical cylinder and is rigidly coupled to a supported structure; each joint is supported by a pedestal plate having a slightly sagged upper surface which consists of three surfaces gradually transforming one into another forming a central concave area, an intermediate convex area, and a boundary concave area. The force of gravity will keep a superstructure in its pre-earthquake location on the pedestal plate until the magnitude of the earth movement exceeds a certain threshold. When the intensity of earth shaking builds up, the foundation will slip aside under the superstructure, the consumable cylinder eventually will shift into the convex area of the pedestal plate surface and the system will activate its softening ability. As a result, a transfer and accumulation of earthquake energy in the superstructure will be significantly curbed.
