Abstract:
A damping foundation (S), comprising a base stand part (1) interlocked with a lower structure (B) and a movable stand part (2) interlocked with an upper structure (G), the base stand part (1) further comprising a rigid base stand (6) having a sliding surface on the upper surface thereof, columnar members (7) vertically installed on the base stand (6), and a restrained beam (8) installed across the upper parts of the columnar members (7), the movable stand part (2) further comprising restrained holes (18) for accepting the columnar members (7) formed above the upper surface of the base stand (6) with moving clearances (&agr ) provided in a sliding direction so that the upper surface of a movable stand (9) can be uniformly press-restrained by the contact thereof with the restrained beam (8) to allow a movement only in the sliding direction, wherein a return mechanism formed of spring materials (22) is installed between the columnar members (7) and the movable stand (9), whereby when an earthquake motion acts on the damping foundation (S), the damping foundation (S) can cope with the movement on a horizontal plane in all directions, and can rapidly damp the earthquake motion.
