The results of comparative calculations of the length of anchoring and overlapping of rebars as well as bending reinforced concrete elements according to SP 63.13330.2012 “Concrete and reinforced concrete structures. Actualized edition of SNiP 52-01–2003” and SNiP 2.03.01–84 “Concrete and reinforced concrete structures” are presented. The necessity to increase the reinforcement (up to 40%) due to the changed methods of calculation in a new SP 63.13330.2012 as a result of the mass use, at present, of reinforcement with a double-side crescent (European) profile instead of the reinforcement with ring profile according to GOST 5781–82 “Hot-rolled steel for reinforcing reinforced concrete structures” previously used and having a better adhesion to concrete, is established. The introduction of new efficient reinforcement with four-sided (four row) periodic (screw including) surface profile developed in Russia into mass construction makes it possible to ensure high efficiency of design and construction from reinforced concrete as well as improve the competitiveness and export opportunities of domestic reinforcing bars.
