Allocation of zones with different responses of ground movement individual indicators to standard seismic impact

The paper presents the results of calculating vibrations soil strata using ZOND- (linear) program. Accelerograms earthquakes recorded in Tbilisi (12/14/2000) and Athens (09/7/1999) on rocky soils were set as a standard seismic action bedrock loose layer. maximum amplitudes records real spectrum areas considered movement indicators. ratios presented indicators to corresponding values initial calculated. obtained form indicators’ for under consideration used differentiate by their response action. Differentiation was carried out three groups according value this ratio. zones reaction identified. sites third group are tentatively assigned most dangerous terms seismicity. Due fact that calculations based linear-elastic representation soils’ behavior, typical small deformations, data preliminary methodological nature will be refined future.
