Calculation method of the longitudinal crack resistance of prestressed flexural elements with high strength AT-1200 (AT-VII) reinforced steel

The article reveals the results of experimental and theoretical studies of the stress-strain state of prestressed concrete flexural elements with thermo-mechanically strengthened At-1200 (At-VII) reinforced steel before exploitation transfer force from the reinforced steel onto the concrete. The article presents the calculation technique of the longitudinal crack resistance of the bearing beam sites as an additional basis for the design and manufacture of prestressed flexural members with At-1200 (At-VII) rod rebar, which represents today the most promising class of high-strength reinforcing steels.
