Assessment of the Effect of Resonance Properties of Soils during Seismic Microzoning

Seismicity is one of the natural hazards characteristic of the Russian Federation territory. Seismic effects cause significant fluctuations not only in the surface of the earth but also in the buildings located on it. As is known, each construction has its own oscillation period, and when it coincides with the predominant period of seismic impact, a resonance effect may occur, which consists in a sharp increase in the amplitude of the oscillations. The paper shows examples of the resonance effect on the calculation of expected seismic impacts.
