At the present stage of development, the diagram method for calculating rod elements made of reinforced concrete has a number of disadvantages, which is due to the lack of a single holistic theory. The paper attempts to propose its foundations. For this purpose, the most General structure of the theory has been developed, and a three-level computational model has been proposed, hierarchically built on the principle of the computational scheme discretization: level 1 - “element” - the rod design model, built according to the well-known rules of construction mechanics; level 2 – “cross” – enhanced non-linear (discrete) deformation model, adopted by BC 63.13330 with some significant author’s clarification; level 3 – material – the standard samples’ analysis model of concrete and rerod subject to the axial compressive action or tensile static short-term load or under static short-time load, pure shear (to describe proposed Jenny more deformation curve of concrete). A detailed algorithm for the relationship of models at all three levels is described.
