Currently, seismic isolation technologies are becoming increasingly widespread in earthquake engineering. The technology, known since ancient times, has been developed in the modern world. The effectiveness of various seismic protection technologies used has been repeatedly confirmed after strong earthquakes in many countries of the world, including Russia. That is why scientific engineering does not stop working to improve the seismic protection of buildings and structures. The article presents the main conceptual seismic protection systems, examines existing design solutions for the implementation of seismic isolating devices, taking into account the peculiarities of their operation during earthquakes, since the reliability of the operation of seismic protection systems largely depends on the characteristics of the seismic impact, its frequency component, direction, intensity, etc. The systems developed and used in Russia currently have economic and social efficiency, making it possible to achieve, in comparison with traditional structures, an increase in the seismic reliability of structures, a reduction in the cost of anti-seismic measures, a reduction in damage from earthquakes, and more accurate assessments of investment and insurance risks.
