Abstract

This article deals with the application of an active seismic protection system in the form of a seismic isolation sliding belt at the foundation level to ensure the seismic stability of a building or a structure. The type of seismic protection studied in this paper is simpler in design, cost-effective, and at least as efficient as widely used metal-rubber supports (MRS). Currently, the considered seismic isolation system does not have an adequate mathematical model to describe its operation in the building-seismic isolation-foundation-base system. The efficiency of using a seismic isolation sliding belt to ensure seismic stability of a structure was studied as exemplified by a cast in-situ reinforced concrete building with a varying number of stories (three-story, five-story, nine-story, sixteen-story building). As a result of the calculations, the relative displacements and accelerations and the intensity of stresses in the most loaded structural element were obtained. The analysis of the obtained results shows the efficiency of using a seismic-insolating sliding belt at the foundation level to ensure the seismic stability of buildings and structures.
