The calculation methodology presented in the program LIRA is based on the theory of academician N I Karpenko about reinforced concrete structures and their deformations. As an additional option for calculating and constructing elements in the program, the method of Wood’s theory. At the same time, the results of reinforcement calculated according to these theories are significantly different, while the use of any of these theories is allowed by normative documents binding on the territory of Russia and the final choice of theory depends only on the experience of the engineer. The aim of this work is to identify the features of calculating the distribution of reinforcement according to the theories of Wood’s and Karpenko’s. The results of the study of reinforced concrete floor slabs loaded with a constant uniformly distributed load with articulated support on short sides are obtained. The study showed that reinforcement according to the theories of Karpenko’s and Wood’s differs mainly by 10 and in environs of consolidation by 70%. The results were analyzed.
