Abstract
Calculation features of biaxial bending reinforced concrete elements by the deformation-force model of their resistance are considered. Attention is focused on the disclosure of the internal static uncertainty of the cross-section of these elements by means of additional equations and hypotheses: the analytic dependence of the "moment-curvature" state diagram, the functions of compressed concrete limiting deformations, the hypothesis about the connection of the stress-strain state of biaxial bending elements with the neutral line inclination angle. Three ways of determining its initial value are proposed: by the condition of materials elastic work; by the elliptic dependence hypothesis of the obliquely bent element stress-strain state parameters on the neutral line slope angle; according to the proportional dependence hypothesis of the biaxial bent element stressstrain state parameters on the neutral line slope angle
