    Abstract. The article discusses the issues of reducing reliability coefficients for materials, in particular concrete and reinforcement. The ways of increasing the economic efficiency of reinforced concrete structures, taking into account reserves of strength characteristics of materials, are presented. A study of the reserves contained in the reserve coefficients has been carried out, taking into account the possibility of a special limiting condition in the structures, in which the operation of the structure is unacceptable or difficult. Analysis of regulatory documents, experimental studies and calculations have shown that, subject to compliance with all regulatory requirements laid down at the design stage, as well as taking into account the actual characteristics, the structures have reserves for strength and deformability. Based on the results of the analysis of reserves of building structures, it is proposed to reduce the reliability coefficients for materials, while increasing the responsibility of plant laboratories for the control of damage indicators, as well as to introduce an intermediate gradation of reinforcement classes.
    Keywords: reinforced concrete structures, limiting condition of the structure, reliability coefficients, reserves of strength characteristics, deformability, concrete, reinforcement
