The purpose of this work is the qualitative and quantitative identification of the unloading effect in the beams of direct coffered floors from the action of torques. To solve the problem in the computer complex SCAD, the bending and torsional moments in the beams of a direct coffered floor hinged along the contour with a plan size of 8.0 8.0 m with different widths of the beams installed with a step of 1.0 m were determined. As a computer model, a rod finite element model of beams of rectangular section with a direct application of a linear load to them according to the law of a triangle was used, as the most accurate finite element method. Analytical calculation of the structure is carried out. The calculation data of computer models showed that as the width of the beams increases, the torques in them increase, while the span bending moments decrease. The width of the support contour beam affects the support bending moment of the span beams, which occurs at the point of their joining. The paper presents graphs of the dependence of the values of the span bending moment, the support moment and the torque on the width of the caisson beams. The analytical method for calculating coffered floors does not take into account the rigidity of the support contour, the presence of torques in the beams, their effect on bending span moments and deflections of the structure. This is one of the reasons for the discrepancy between the data compared by the researchers.
