The results of the study of the influence of the rigidity of the soil base on the dynamic characteristics of structures, namely the frequency, modal mass, oscillation forms are given. Two types of structural solutions of structures are considered: symmetrical in plan with respect to one axis of the building and symmetric in plan with respect to two axes of the building. The parameters for modeling the stiffness dynamic characteristics of different types of soil bases are determined.
