This article analyzes the existing solutions for applying special seismic protection to building complexes. The PSTU developed at the “Buildings” department designed model for a number of buildings in a seismic region in the North Caucasus with seismic isolation, made in the form of rubber-metal supports. Preliminary structural calculations have been performed showing that the use of such a seismic protection system helps to reduce the load on the building while saving money on seismic strengthening.
