Studying technological and functional characteristics of long-term quickly erected geodesic dome shelters for the needs of EMERCOM of Russia

Purpose. A technological and functional analysis of features of structural-power schemes (SPS) of long-term quickly erected geodesic dome shelters for the needs of airmobile groups of EMERCOM of the Russian Federation was carried out. The results of the interdisciplinary study of the two types of SPS geodesic dome structures with expanded capacity were presented. Methods. Based on the calculations results, the curves of the technological and functional features of the investigated types of SPS of long-term quickly erected geodesic dome shelters for the needs of airmobile groups of EMERCOM of Russia were obtained, which ultimately resulted in making a comprehensive comparative evaluation by the use of a graphic-analytical method. Findings. The outcomes of the two variants of SPS complex comparison according to technological and functional criteria allow us to confirm the undeniable advantages of the second type of SPS (a hemisphere based upon a cylinder) compared to the firstone (3/4 segment of the ball). Considered in the article the structural and technological solutions resulting from applying an integrated approach will allow designing new, more comfortable and technically advanced long-term quickly erected dome shelters by increasing the construction and mobility efficiency; by simplifying the erection process due to the structural elements unification, visual control of the correct assembly during the structure erection, control of the technical condition of the structure during operation. The given factors are especially relevant in the context of solving the problems of accommodating large groups of people who urgently need to be provided with long-term accommodation in emergency situations. Research application field. The results obtained will make it possible to adequately choose the type of geodesic dome SPS to create long-term shelters to ensure more efficient operations of airmobile groups of EMERCOM when eliminating consequences of emergencies. Conclusions. As a whole, these circumstances make the second variant of SPS preferable from the point of view of ensuring simplification of the technology for erecting long-term shelters, which is especially important for a large-scale construction. The use of the second type of SPS as quickly-erected long-term geodesic dome shelters in the future can increase the effectiveness of EMERCOM airmobile groups when eliminating consequences of emergencies.
