Abstract
The article provides a calculation model of the complex resistance of reinforced concrete box-section structures on the combined action of bending and torsional moments, longitudinal and shear forces after the formation of spatial cracks.
The calculation model allows taking into account all the main external influences for a reinforced concrete element of a box rectangular cross section: torsional (T) and bending (M) moments, shear (Q) and longitudinal (N) forces. In this case, the action of the torsion and the shear force is reduced to the action of the flow of tangential forces along the rectangular contour of the section.
