description: The current work is devoted to the study of constrained torsion in joints of flat thin-walled rod systems. The research set the following goals: 1. Assessment of the influence of a gusset plate on the bimoment transmission through the joints made of thin-walled profiles. 2. Verification of the method of accounting for the bimoment in the joints of flat thin-walled rod systems proposed by V.A. Rybakov and D.O. Sovetnikov. 3. Investigation of the bimoment transmission in the joints made of thin-walled profiles of different stiffness. 4. Investigation of the bimoment transmission in the joints made of thin-walled profiles connected at different angles. 5. Consideration of structural elements in the study of the bimoment transmission in the joints made of thin-walled profiles. The main research method in the thesis is the finite element method. Several software programs (ABAQUS, SCAD, Maple) are used in the work in order to design and calculate rod and solid finite element models of various joints and structures made of thin-walled profiles. As a result, the method of accounting for the bimoment in the joints of flat thin-walled rod systems proposed by V.A. Rybakov and D.O. Sovetnikov was verified. The areas of application of previously known hypotheses are determined: 1) the hypothesis of A.R. Tusnin; 2) the hypothesis of A.S. Gorodetsky and others. By the design and calculations of solid finite element models, the character of the bimoment transmission was investigated in the joints made of thin-walled profiles: 1) of different stiffness; 2) connected at different angles; 3) taking into account structural elements (gusset plate, corners, bolted connections). The recommended values of the âcoefficient of the cross-sectional axis rotationâ in the joints made of thin-walled profiles connected at the angle of 90Ë have been determined.
