Analysis of subsoil modeling influence on dynamic characteristics of reinforced concrete building

The paper is devoted to issues related to creation of subsoil models. At the beginning of the paper, the model of the building chosen for the analysis was described. The procedures for calculation of different models of the subsoil were also described. The final part of this paper presents results of the analysis of natural frequencies of reinforced concrete building with regard to the different models of the interaction between subsoil and the structure, and the conclusions drawn from this analysis are also presented
