Abstract. In the modern world, where infrastructure plays a key role in economic development and ensuring the comfort of life for the population, special attention is paid to the quality and durability of structures such as bridges. Composite bridges are becoming increasingly popular due to their unique properties, such as high strength, stiffness, low weight, and others. However, despite their advantages, the operational performance of composite bridges can significantly depend on the climatic conditions in which they function. This article is devoted to the study and analysis of the dependence of the operational characteristics of composite materials on various climatic factors.

The article begins with the definition of the term «composite materials». The authors emphasize the key properties of composites that make them attractive for bridge construction, such as high strength and stiffness, low weight, corrosion resistance, architectural appeal, and others. At the same time, they note that, despite these positive characteristics, climatic conditions can cause deformations and a decrease in the strength of these materials.

In the main part of the article, the influence of climatic factors, such as temperature, humidity, ultraviolet radiation, and corrosion, on the durability and reliability of composite bridges is examined. The authors analyze the consequences of the impact of these factors on the mechanical properties of the material. The article also discusses methods for assessing the influence of climatic conditions on the operational performance of composite bridges. These methods include laboratory testing, field studies, modeling, and forecasting.

In conclusion, the authors emphasize the importance of considering climatic factors and a comprehensive approach in the design and operation of composite bridges, as well as the need to develop recommendations for improving their resilience and durability under changing climatic conditions.
