Summary. The article deals with rational way of determining the oblique compressed reinforced concrete elements deflection, based on the direct use of curvature function of the generalized phase diagram.

Keywords: reinforced concrete, oblique compression, elements, structures, deformation, stiffness, curvature, deflections.

Summary. The paper deals with the basic principles of the generalized model of concrete and reinforced concrete elements and structures deformation, based on the main patterns of forces and stresses internal redistribution not only between their sections, but also between definite sections of these fibers.

Key words: reinforced concrete, elements, structures, model, deformation, redistribution, forces, stresses.
