Today, the role of calculating building structures for special loads and impacts has significantly increased. However, often performing such a calculation is complicated due to the insufficient development of the mathematical apparatus, as well as insufficient awareness of the nature of the origin and nature of the spread of loads. For this reason, the creation of adequate calculation models is almost impossible. A special place among calculations for special loads is occupied by dynamic calculations for seismic, impulse impacts of various nature, shock loads, including explosive ones. Vibrations can be produced by large industrial enterprises, highways, railways, and the subway, which leads to damage or even destruction of structures. Extreme loads from blast waves have become a reality today, which requires the design of protection elements for ground and underground structures. An integral and perhaps the most important step is the assessment of the external impact perceived by the structure. In order to calculate the building, it is necessary to take into account the presence of a source of vibration or the occurrence of an impulse, the rate of its growth, the physical and mechanical properties of the soil, its behavior when changing the direction of displacements, the specific features of the territory on which the structure is located. The purpose of the work is to create a theory and methods for numerical research and analysis of the processes of distribution of intensive and explosive dynamic loads within continuous media, taking into account large plastic deformations, the influence of the deformation rate on the behavior and strength parameters of soils, and the determination of the criteria for their destruction. popup.nrat_date 2025-03-25 Close
