Abstract
The method based on separation of the earth & structure. In this method applied force will be decreased during earthquake
due to separation of structure & earth by making base of structure or floors flexible and applying energy dampers component
& separator layer usually have a higher natural period than fixed support natural period which cause the acceleration of seismic
spectrum to decrease and a kind of short cylindrical seismic cushion with one hole or more and steel plates with stiffen rubber
between them are mundane in seismic separators and because of depreciation of energy by seismic separators and this method is
used for stiff structures with high and short frequencies with heavy forces but in this technique the use of seismic separator in soft
soils due to possibility of equalization of period and exacerbated phenomenon or Resonance isn’t recommended and choose period
must be far from earth movement period, if it’s possible.
Keywords: Structure, Earthquake, Seismic Spectrum, Steel Plates
