Approaches to proportioning of buildings and structures, based on direct numerical integration of dynamic equations, continue to be relevant. For this purpose realistic or artificial accelerograms are used. Probabilistic methods of calculation are based on generation of artificial accelerograms as random-process realizations. There is proposed method of generation of artificial accelerograms, based on representation of correlation function as sum of cosine-exponential summands. Approximation parameters are defined on the basis of least squares method through the use of Curve Fitting Toolbox CKM MATLAB package. Artificial accelerograms are generated by utilizing design formula of autoregression (moving average). Accuracy of generation is illustrated by computation of spectral curves.
