The behavior of civil buildings of various design solutions in conditions of the combined spread of permafrost soils and seismic impacts

Introduction. The northern climate zone occupies significant territories of the Russian Federation, which today are very promising, as they have a high potential for development, due to the rich reserves of minerals, rare metals and precious stones. With the extensive development of the extractive industry in these remote territories, the question arises in parallel of the construction of civilian facilities, which include public and residential buildings for various purposes, the main task of which is to ensure reliable, safe and comfortable operating conditions. Part of this zone, which affects the regions of the Far East, Western and Eastern Siberia, is in difficult conditions, such as the combined combination of permafrost and high seismic activity, the score of which varies from 6 to 10 points. That is why these territories dictate special requirements and conditions for design and construction, as well as pose complex tasks for engineers that require non-trivial approaches and solutions. Materials and methods. To assess the behavior of civil buildings of various design solutions in conditions of the combined propagation of permafrost soils and seismic impacts of various frequency compositions, a numerical study was conducted using the method of direct integration of the equation of motion over time. Results. The article presents the results of computational studies of civil buildings of various design solutions in conditions of the combined spread of permafrost soils and seismic impacts. It is shown that the earthquake resistance of civil buildings with various structural solutions in conditions of permafrost soils and high seismicity differ significantly from each other. This indicates the need for a detailed justification of the design decisions of civil buildings for the conditions under consideration, taking into account the properties of permafrost soils
