This article presents the results of a study on the random variability influence of soil deformation parameters - elastic modulus, Poisson’s ratio - on the dynamic characteristics of a building. The spatial finite element system “building - pile foundation” is considered, taking into account the reduction in the acceleration of ground vibrations with depth. The probabilistic calculation of the system is carried out by the Monte Carlo method, the random parameters of the subgrade are taken to be distributed according to the normal law. Statistical characteristics of free frequencies of system vibrations were obtained, it was found that within the same soil type, it is possible to realize system vibrations with a predominance of both the 1st and 2nd forms.
