The paper presents the results of numerical modelingof the dynamic problem related to the calculation of abuilding model with a seismic-isolating belt. There hasbeen developed a mathematical model describing theinteraction of structural elements of the building with theseismic isolation system under various dynamic effects, including seismic vibrations of different intensity and frequency characteristics. The results obtained under the action of harmonic loading are presented. By applying the method of successive approximations, the system of differential equations of motion is transformed into a system of algebraic equations, which is solved at each time step. The results of numerical modeling at different locations of the sliding plane are found. The obtained results will be used in further experimental studies on physical models of buildings with the use of vibration platforms. This approach will allow not only to confirm the adequacy of the mathematical model, but also to obtain additional data on the performance of seismic isolating structures under conditions close to real seismic effects. The obtained data can be applied to the design of buildings in earthquake-prone areas to improve their stability and safety.
