The method of experimental tests of reinforced concrete beams, strengthened additional prestressed reinforcement under load (at different levels of prestressing andactive load), with the corresponding control a strength of normal cuts and prestressed additional reinforcement.Developed and presented a program of experimental tests to assess strength parameterof normal cutsexperimental reinforced concrete beams,reinforced prestressed reinforcement under load. Based on the research program developed design prototypes and selected characteristics necessary materials. Analyzed a modern positionand trends in renovation and reconstruction of buildingsand structures elements.Processed scientific works of scientists of many countries of the worldin the branch of experimental studies strengthening of reinforced concrete constructions. Developed a simple and effective way electrothermalprestressing additional reinforcement of strengthened constructions.Madea corresponding conclusions to work.Posted list of scientific publications in the field strengthening of building constructions, and normative literature, used in writing this scientific work.
