Abstract. The article presents the results of the analysis of experimental studies of the stress-strain state of reinforced concrete beams at the stage of load-bearing capacity reduction, showing the presence of reserves in strength and deformability. The work was carried out in order to clarify the criteria of a special limit state for bendable reinforced concrete elements. A description of the experimental unit is presented. Principal approaches for determining complete (including stages of concrete softening of the compressed zone) "moment-deflection" diagrams are considered, as well as approaches to determining stresses in the section of a bent reinforced concrete element at all stages of deformation. For this purpose, technical means have been developed to measure deformations in the section of a reinforced concrete element during its destruction. Experimental data have been obtained to assess the complete deformability of bendable reinforced concrete elements depending on the reinforcement and strength of the concrete.
Keywords: reinforced concrete structures, deformation diagrams, special limit state, criteria, experimental work
