CONICAL SLIDING-FRICTION SEISMIC ISOLATION DEVICE

WIPO Patent Application WO/2015/068964

A1

Provided is a conical sliding-friction seismic isolation device which is easy to manufacture, can dramatically increase a support area during sliding friction, and has various friction force-displacement loops. The conical sliding-friction seismic isolation device has a conical sliding-friction surface having a first friction surface and a second friction surface which is a concave conical surface arranged around the circumference of the first friction surface, such that the conical sliding-friction surface has a part of which a surface inclination changes in the center of the first friction surface or at a boundary between the first friction surface and the second friction surface. A bearing block assembly comprises: a rotating block provided to be rotated with respect to an upper member or a lower member according to a position which comes into contact with the conical sliding-friction surface; and a variable-shape friction part which is coupled to the surface of the rotating block and of which the surface shape changes according to the shape of the facing conical sliding-friction surface by the load of an upper structure when mounted on the part at which the inclination has been changed.
