| Title of the article | Features of external reinforcement technology for strengthening load-bearing structures of buildings |
| Abstract. | Problem statement. The development of the construction industry and increasing demands on the functionality of buildings and structures necessitate the development of effective methods for strengthening load-bearing structures. The need for reinforcement may be driven by such factors as changes in the building’s functional purpose, increased loads, degradation of material properties, and the need for repairs after emergency situations. Traditional reinforcement methods (installing casings, extending sections, etc.) often have a number of disadvantages: increased labor intensity, increased structural weight, and interruptions in the facility’s operation. The objective of this work is to develop and analyze a technological solution for strengthening reinforced concrete floors and coverings with composite materials. The tasks of the work are to study this reinforcement technology using external reinforcement systems based on composite materials, to investigate the deformation properties of reinforced structures, and to evaluate the effectiveness of this technology. Results. It has been established that the application of external reinforcement technology based on composite materials significantly increases the load-bearing capacity and improves the operational characteristics of structures. A technological solution is proposed based on strengthening reinforced concrete structures of floors and coverings using carbon strips and carbon fiber reinforced plastic plates. This technology effectively strengthens reinforced concrete floors and coverings with minimal disruption to the structural integrity of the elements, while simultaneously preserving their architectural appearance and reducing construction time. Conclusions. The applied technology for strengthening reinforced concrete floors and coverings, based on external reinforcement of structures with composite materials, has high efficiency while simultaneously ensuring operational reliability, which allows this technology to be recommended for wide application in construction practice. |
