In accordance with current conditions, it is necessary to change the aim of buildings and structures in which a large number of reinforced concrete elements that undergo complex stress-deformed states are used. The task for researchers is to determine the residual bearing capacity of the element with uneven damage, making it possible to choose the most optimal calculation option and select materials for optimization, preservation of strength, and durability. Also, a special role is played by the study of the impact of damage and defects, which cause a stressed - deformed state that cannot be predicted by calculation. Methods of determining the residual bearing capacity of reinforced concrete elements with various types of damage are considered. It also provides a detailed analysis of the most common defects and damages in reinforcement concrete structures, different types of corrosion.
