Abstract. For the selection of reinforcement in reinforced concrete structures, software systems are used, in which various algorithms are adopted, depending on the applied theory of reinforcement selection. The implementation of even identical theories of calculation in software systems are different, so the important issue is the justification for the selection of the reinforcement and checking of the executed reinforcement. The paper presents the results of the calculation of reinforcement of beamless and beam floor slabs. Calculations were made with due regard the first limit state only and as well as calculations for the first and second limit state. Software complexes LIRA-SAPR, SCAD, LIRA 10 were used for calculations. The presented results of reinforcement are verified by calculations according to the current SP 63.13330.2012 " SNiP 52-01-2003 Concrete and reinforced concrete structures. Basic provisions". On the basis of the results obtained, the conclusion about the adequacy of the applied reinforcement is made, recommendations for carrying out verification calculations of structures are given.
