Study of the seismic isolation sliding belt: the case of a monolithic reinforced concrete building

Abstract

Abstract This work highlights the application of an active seismic protection system using a sliding belt in the foundation to protect buildings and facilities located in earthquake-prone areas. The widespread type of seismic protection using rubber-metal supports (RMS) is complex and sometimes not cost-effective. The considered method of seismic protection using seismic isolation sliding belts has a number of advantages over the other types of seismic protection. However, the considered seismic isolation system still does not have an adequate mathematical model describing its action in the building-seismic isolation-foundation-base system. The study covered the efficiency of applying the seismic insulation sliding belt through the example of a 16-story monolithic reinforced concrete building. As a result of the calculations, the absolute accelerations, velocities, relative displacements, and intensity of stresses in the considered structure were obtained. An analysis of the calculations indicates the efficiency of seismic isolation using a sliding belt in the foundation for buildings constructed in earthquake-prone areas.
