This article systematizes reinforcement methods based on their operating principle and the materials used, identifying key trends: the dominance of technologies based on composite external reinforcement materials and the active development of hybrid systems. A classification scheme has been developed that allows for the informed selection of reinforcement methods based on the technical condition of the structure and the desired result.
The article demonstrates the high effectiveness of composite materials in increasing strength and seismic resistance with a minimal increase in cross-sectional weight. It is determined that traditional methods (reinforced concrete casings, shotcrete) remain relevant when a significant increase in rigidity is required. Promising areas for implementation are identified: the adaptation of international standards, the development of domestic equivalents of high-performance composites, and the creation of digital reinforcement models.of investments in interests of the organization and development of new production on available floor spaces. The most important organizational economic targets of a diversification of management are presented by innovative activity of the industrial enterprise.
