description: The theme of the final qualification work: "Evaluation of the effectiveness of the use of composite materials in span structures of bridges". The work is devoted to substantiating the expediency of using composite reinforcement in span structures in comparison with metal reinforcement. Purpose of the study. Evaluation of the effectiveness of the use of composite materials in the composition of reinforced concrete span structures. Research objectives: 1. Review and analysis of the results of the study of composite materials and bridge structures by domestic and foreign authors. 2. Perform an experimental study of samples for bending from a uniformly distributed load over the area reinforced with various reinforcement. 3. To analyze the stress-strain state of the span structure in the Lira-SAPR software to select reinforcement and evaluate the effectiveness of the use of composite reinforcement. In the process of preparing for the experiment, we analyzed the main physical and mechanical properties of fiberglass reinforcement, its position in the construction market, all the advantages and disadvantages. They made a comparison with steel reinforcement and came to some conclusions, which were then confirmed with the help of calculations and experiment. An analysis of the stress-strain state of the load-bearing structures of a span structure fragment was carried out in the Lira-SAPR software. With the help of the software, we chose the necessary reinforcement, calculated the required quantity and compared the cost and weight when using steel and fiberglass. The experimental part was carried out in the laboratory, where we tested prototypes for bending under a uniformly distributed load. The samples were part of a span structure with steel, fiberglass and basalt-plastic reinforcement. As a result of the work, it can be concluded that the use of composite reinforcement in secondary elements, namely in pavement elements with a small span, is possible and can reduce the cost of their reinforcement.
