On models of ground vibrations in strong earthquakes

Objective. The purpose of these studies is to determine, on the basis developed models describing seismic impacts, most acceptable for acceptance from point view accuracy description oscillation both in shape envelope and duration frequency characteristics. Method. use empirical soil fluctuations as a random process has been considered number papers. This paper presents main simplifying assumptions used this approach. validity some difficulties encountered modeling are investigated. Result. A methodology assessing reliability proposed impact proposed. method takes into account - geological characteristics, well spectral data instrumental recordings known earthquakes. Conclusion. model, approximating function, should be determined by degree responsibility building.
