There are two types of "earthquake-proofing": seismic isolation and earthquake-proofing.
Seismic isolation" is a method of reducing the transmission of shaking by inserting seismic isolators at locations where shaking is transmitted.
The classification of "seismic isolation" is divided according to the construction location.
Building seismic isolation: between ground and building foundation
Base-isolated floor: between frame slab and mounted equipment (entire room or part of room is base-isolated)
Equipment seismic isolation: between finished floor and mounted equipment (installed under the equipment to be seismically isolated)
base-isolated floor
Various types of seismic isolation floors can be provided according to the conditions of the installation site and the direction of shaking to be reduced.
Equipment Seismic Isolation
In general, for equipment seismic isolation, the standard for seismic isolation is about 250 gal.
By installing in equipment seismic isolation. Seismic intensity 7 (1000 gal) can be reduced to intensity 5 or higher (250 gal).
earthquake-resistant frame
It can also provide seismic resistance for racks housing telecommunications network equipment. This sliding type is convenient for maintenance.
