Influence of nodal connection stiffness on the mechanical characteristics of the rack

The article is devoted to the evaluation of the torsional stiffness of the beam junction. The influence of the connection on the bearing capacity and stability of the construction of a thin-walled rack is analyzed. As an example, we consider models of beams with a length of 1.5 m. Torsional stiffness values for a beam-stanchion connection under extreme loads are obtained. Results of full-scale tests will be compared with the results of electronic calculations made in a specialized software package.
