A calculation model of reinforced concrete structure at bending with torsion has been constructed. The deformation effect has been discovered, the physical essence of which is the additional deformation effect when the continuity of concrete and reinforcement discontinuity is broken for an ellipsoid-shaped crack. A special two-cone fracture mechanics element for a single strip is used for the crack. The Saint–Venant principle is fulfilled from the adhesion of the peri-armature zone, where the deformations of the concrete adjacent to the cracks change their sign to compression. In helical, elliptical and harmonic spatial cracks, the crack opening, longitudinal and transverse shifts are determined through the guide cosines. When analyzing the complete picture of crack formation during loading, the levels of spatial cracks are distinguished when comparing the functional or discrete value. Crack opening is the accumulation of relative conditional concentrated mutual displacements of reinforcement and concrete on the sections and banks of the crack. which is calculated using the Thomas-Kolchunov hypothesis. The stiffness of spatial bending cracks with torsion in elastoplastic compressed concrete is obtained by projecting linear and angular deformations (stresses) using tensor diagrams. The stiffness of spatial bending cracks with torsion in elastoplastic compressed concrete is obtained by projecting linear and angular deformations (stresses) using tensor diagrams. Approximation of rectangular cross-sections using small squares in matrix elements for stiffness characteristics with tensile medium working reinforcement is performed.
