description: Topic of the final qualifying work: âThe use of composite materials in the span structures of road bridges.â The study is devoted to the possibility of using fiberglass reinforcement for reinforcing bridge spans. During the work, the following tasks were solved: 1. Analysis of the use of composite materials in bridge construction. 2. Study of the strength characteristics of span structures using composite materials. 3. Calculation of the span bridge structure. 4. Technical and economic comparison of reinforcement of span glass with fiberglass and steel plumbing fixtures. 5. Development of recommendations for the use of fiberglass reinforcement in the construction of bridge spans. Domestic and foreign experience in using composite materials in bridge construction is analyzed. Calculations of the bridge span structure for permanent and temporary loads were carried out. The calculation results show that the designed structure using fiberglass reinforcement meets the requirements of regulatory documents for strength, stability, and crack resistance. As a result, a span bridge design using fiberglass reinforcement was developed that meets all regulatory requirements. An estimate calculation of the span tension device using fiberglass and steel reinforcement was also compiled.
