    Abstact. The results of the analysis of the restoration of damaged bearing structures of buildings and structures located in the annexed territories are presented. Multi-storey buildings with load-bearing masonry walls are considered as the main object of research. The assessment of the characteristic damages to the masonry of the load-bearing walls as a result of mine-explosive impacts is carried out, the features of these damages requiring special reinforcement methods are described. A method of restoration and reinforcement with the use of one-sided applications of shotcrete has been developed, which involves carrying out work on the outer surface of the bearing walls and restoration of the bearing capacity of vertical stone structures. As part of the development of the reinforcement technique, laboratory tests of samples of masonry with reinforcement from shotcrete were carried out, the main physical and mechanical characteristics of shotcrete, including the modulus of elasticity, necessary for numerical modeling and computational justification, were determined. On the basis of a multi-stage calculation performed in accordance with the current regulatory documents, the reliability of masonry walls reinforced with one-sided applications of shotcrete concrete is theoretically substantiated.
    Keywords: reinforcement of masonry, masonry, mine-explosive effects, shotcrete, modeling
