Abstract

Objective. The purpose of these studies is to develop a methodology for assessing the seismic hazard of territories and a methodology for making an optimal design decision based on various criteria, including criteria for quantitative parameters of soil vibrations, taking into account regional peculiarities.Method. Estimation of quantitative parameters of seismic events registered on the territory of the Republic of Dagestan and adjacent areas by analytical and numerical methods. Determination of the reliability of buildings based on probabilistic models.Result. A method for estimating the parameters of soil vibrations based on the processing of instrumental records of known earthquakes, taking into account the characteristics of soils, is proposed. A method for making an optimal design decision is proposed, taking into account the parameters of soil vibrations and other target functions.Conclusion. The analysis of the obtained results showed that with an increase in the thickness of the loose layer, the magnitude of the maximum acceleration increases, the range of unstable fluctuations of the periods at the same time lies in the range of 0.1-0.5 seconds. The construction of buildings should be based on the parameters of the vibrations of the soils of the construction site, taking into account the lithological composition of the soil and other physical and mechanical properties.
