SEISMIC ISOLATION APPARATUS FOR STRUCTURES, METHOD FOR INSTALLING APPARATUS THEREOF, AND SEISMIC ISOLATION MEMBER

摘要

The seismic isolation apparatus 1 is an apparatus for damping the vibrations of an upper section A of a structure with respect to a lower section B of the structure, and provided with a plurality of U-shaped seismic isolation members 10, a first coupling plate 20 to which one end of the seismic isolation member 10 is fixed, and a second coupling plate 30 to which the other end of the seismic isolation member 10 is fixed. The seismic isolation members 10A are placed between the first coupling plate 20 and the second coupling plate 30 in a direction. The seismic isolation members 10B are placed between the first coupling plate 20 and the second coupling plate 30 in a direction oppose to the direction of the seismic isolation members 10A.
