Abstract. Two methods of reinforcing brick structures are analyzed: reinforcement with a steel cage and with composite materials. A technical and economic comparison of these methods and determination of their effectiveness are made. For this, the basic strengthening technology is considered, lists of resources for each strengthening in current prices are given, the comparison of the proposed options by the ranking method is made. In domestic practice, modern methods of strengthening structures, including the use of composite materials have been developed. This kind of strengthening makes it possible to improve the physical and technical bearing characteristics, as well as the stiffness of the structure, in addition the operation characteristics of the building are improved as a whole. One of the "know-how" of this type is glueing composite canvases on the surface of the repaired structures with the use of energy-efficient and environment-friendly, durable adhesive compositions. Currently, the necessary standards and regulations for the use of this method of strengthening are being developed.
Key words: strengthening of brick walls, steel cage, composite materials, list of resources, repair works. - REFERENCES
