dc.descriptionSince the beginning of February 24, 2022, during the year of the war, russia has launched almost 5,000 missile strikes and about 1,000 kamikaze drone attacks on the territory of Ukraine. Unfortunately, the greatest destruction of buildings and structures and a large number of victims are caused by S-200, S-300, X-22, "Iskander" missiles, which cannot be intercepted by the air defense of Ukraine. Therefore, today it remains an urgent issue to establish standardized ground shelters that, in the conditions of hostilities, can block the influence of impact factors (aircraft, missile and artillery fire) and protect people from damage by debris and fragments of building structures. An important aspect that determines the effectiveness of protective structures is the possibility of safe evacuation from them, after the destruction of the building structures of the objects from hitting them with combat shells. This determines the urgency of modernizing and improving existing or setting up new ground defense structures.uk_UA
dc.description.abstractThe article presents the results of mathematical modeling of the impact of the explosion and the corresponding stress-strain state in reinforced concrete blocks of protective structures. The purpose of the work is to establish the safety of the developed protective shelters in the conditions of an explosion during aerial attacks. After conducting the calculations, the results were obtained, which allow to investigate the mechanisms of destruction or loss of integrity of shelter structures and to establish the relationship of these aspects with ensuring the performance of its protective functions under the influence of an explosion. To study the mechanisms of destruction or loss of integrity, the impact of the explosion was investigated. The scientific novelty consists in the development of a new approach to calculations, based on the application of the warhead value of the corresponding projectile in TNT equivalent, the distance of the explosion and the position of the point where the explosion occurs. The determined pressure according to these parameters can be used to study its effect on structures. The practical significance of the research - on the basis of the conducted research, the results of mathematical modeling of the behavior of protective shelters in the conditions of an explosion were obtained, which allow to investigate the mechanisms of destruction or loss of integrity of the structures of the shelter and to establish the relationship of these aspects with ensuring the performance of its protective functions under the influence of an explosion.uk_UA
