Abstract

In the deterministic analysis of building structures, instrumental or synthesized accelerograms are used as initial data. As a rule, earthquake records corresponding to low-intensity accelerograms are available at each site. Very often, instrumental recordings of high-intensity earthquakes are missing. To correct this situation, an algorithm has been developed for modeling low-intensity accelerograms to high-intensity accelerograms using a wavelet transform.
 As an efficiency of this algorithm, a comparative analysis of the reaction spectra of linear 
 oscillators, as well as the pulse and Arias energy criteria for synthesized and instrumental 
 accelerograms was carried out.
