Research overview:
With respect to three-dimensional seismic isolation of structures, the technology concerning equipment/floor structure has been alredy developed and practicized. However, the technology concerinig buildings has not yet been in progress owing to its difficulty. Meanwhile, the necessity for three-dimensional seismic isolation of buildings has recently been discussed in the field of nuclear facilities. This research developed the three-dimensional seismic isolation apparatus with combination of laminated rubber for horizontal seismic isolation and metal-made belleville spring for vertical seismic isolation, and its seismic isolation performance was examined.
