The nature of loads and impacts today, despite the huge number of experiments, both physical and numerical, is still not fully understood. The seismic load is especially difficult to describe and predict. The construction of buildings and structures in earthquake-prone areas is not an easy task for engineers and designers. Having updated data on the seismic hazard of the construction area, antiseismic measures can be taken at the design stage and constructive measures can be used. However, in some cases, constructive measures are not possible, or anti-seismic measures are required with an already erected building or structure. And, since the seismic load is transmitted to the structure through the foundation, it is possible to change the properties of the foundation itself, in particular, to install anti-seismic barriers of various kinds. One type of such a barrier will be discussed in this work. A brief overview of the types of barriers will be given in this work. Of particular interest to the author is the calculation in the finite element analysis software of the base layer model through which the signal passes (that is, the seismic load). Comparison of the alternation of base layers with different physical and mechanical characteristics, as well as comparison of the forms of signal appearance and assessment of the degree of intensity of its attenuation are the purpose of this work.
