This article presents the results of an experimental study of damaged reinforced concrete beams. Corrosion of reinforcement in concrete is one of the main problems of durability faced in practice by civil engineers. Particular attention should be paid to the action of an aggressive environment as one of the most common causes of the introduction of elements into an emergency. The aim of the work is to determine the strength and deformability of reinforced concrete structures without damaging the reinforcement and in case of damage. According to the research program 4 beams were tested. Among them were undamaged control samples with single reinforcement of ∅20 mm diameter and samples with ∅20 mm reinforcement with damages about 40%. The reinforcement was damaged before concreting the samples. The test specimens were tested for bending under short-term load. At the result impact of damage to reinforcement in RC beams reduces the load-bearing capacity. The results are given in the article.
