Deformation of Reinforced Concrete Structures During Bending with Torsion

A computational model of deformation, crack resistance, and strength of complexly stressed reinforced concrete rod structures under the combined action of bending and torsional torques, normal and transverse forces is proposed. Until now, in the design practice, the calculation of reinforced concrete structures under such a stressed state in domestic and foreign practice is carried out using very conditional physical and computational models. It is enough to note that in the United States, a number of European and other countries, the truss analogy model is still used in the calculation of such complex structures. The article presents a solution to the problem of creating a design model of a reinforced concrete element of box section under the combined action of bending and torque moments, normal and transverse forces in the stage after the formation of cracks, which most fully takes into account the specifics of crack formation, deformation and destruction of such elements. In this case, the action of the torque and the transverse force is reduced to the action of the flow of tangential forces along the contour of the box section of the structure.
