Abstract
Both bending and torsional stiffness are the important factors affecting the spatial work of the reinforced concrete engineering structures. While bending stiffness is studied carefully, the torsional stiffness is not sufficiently investigated. This paper studies one of its components, the torsional constant. The accepted in the practice formulae of the strength of materials are appropriate only for thin-walled sections and give a significant error in other cases. That's why the exact technique has been tested on the example of the T-section, which is one of the most common cross-sections applied in engineering (for the reinforced concrete overlaps, bridge superstructures, etc.). The results of the calculation by different methods have been compared. The essential error has been proved.
