A method is developed to reproduce seismic impact on structures based on the recorded earthquake accelerogram and upon the condition that the maximum values of seismic inertia forces under real seismic impacts and in case of simultaneous action of groups of powerful vibratory machines installed at different levels of the structure are equivalent.

The parameters of the vibratory machines, such as mass-eccentricities and their distance to the rotation axis, are determined depending on the dynamic characteristics of the structure, locations of the vibratory machines and the accelerogram of the earthquake being reproduced by the formula derived in the article.
