Calculation of the strength of reinforced concrete beams by inclined sections is always a difficult task. There exist various methods of calculating the carrying capacity of reinforced concrete beams along inclined sections, each of them having its own advantages and disadvantages. However, most of the constructed and developed methods are based on the theories or models used in ACi 318, EC 2 and SP 63.13330. This article discusses methods for calculatingreinforced concrete beams along inclined section without stirrups (transverse reinforcement) according to ACi 318-19, EC 2 2004 and SP 63.13330.2018 standards. A comparative analysis with experimental results was performed. The aim of the study is assessing of the effect of longitudinal reinforcement on the shear bearing capacity of beams, improvement of the methodology for calculating the strength along inclined sections of reinforced concrete beams, taking into account the effect of longitudinal reinforcement and shear span-to-depth ratio.
