AbstractAbout the AuthorReferences
Rebar of An600C class made of 20G2SFBA steel has been developed and is manufactured by Cherepovets Steel Mill of PAO “Severstal”. Due to the chemical composition including niobium and vanadium, this thermo-mechanically hardened steel has high corrosion resistance, fire resistance and ductility. Research in the use of the rebar of An600S class in prefabricated reinforced concrete structures has shown the possibility to reduce the consumption of rolled product in structures with frame-reinforced concrete frames by series 1.020-4 and 1.420-35.95 with overlappings from multi-hollow slabs. Reduction in the consumption of reinforcing bars reaches 13.3% in comparison with rebar of A500C class , and in buildings of the series 1.020-1/ 83 (87) – 9% in comparison with the rebar of A500C class. For multicore slabs, the reduction in consumption of the reinforcement used in the frames of these series in comparison with rebar of A500C class can reach 21%, and when compared with the widely used rebar A600, the savings can be 7%.
