Substantiation of an efficiency of the work of special constructive units forming a seismo-protective belt set in the foundation of the building and aimed to decrease seismic loads during the earthquakes, is given in the paper. Research is carried out on the basis of spatial model of a building, presenting a high box-like structure with intermediate floors and real geometry. Spatial models and used finite element discretization allow the authors to consider a complex dynamics of the building under multi-component seismic effect. The study of dynamic characteristics — frequencies and modes of natural vibrations and relative deformation, listed in normative documents, when determining a conditional seismic load, is carried out on the basis of comparison of results obtained for two spatial models of 9‑storey building; these models differing in boundary conditions in the foundation: standard building (on rigid foundation) and the building on seismic-protective supports. The comparison was performed also with data of field experiments for two similar buildings, its results affirmed the positive conclusions on efficiency of the installation of seismo-protective belts.
