Annotation:
 For deterministic analysis of building structures it is necessary to set real or synthesized accelerograms as input data. This analysis requires considerable time, as it is performed by a step-bystep method. Real accelerograms can be of considerable length and
require a lot of calculations. As a rule, accelerograms have maximum values of amplitudes on a small temporal site. The article considers the possibility of using only a part of the accelerogram without loss of adequacy of calculation of seismic reactions of inelastic systems. The method of truncation of extended earthquake accelerograms for the analysis of nonlinear systems is defined. The necessity of application of the energy criterion is shown. Nonlinear oscillators for different materials are considered.
