Annotation: A working hypothesis relating to the structural analysis of the spatial structures from thin-walled bars with open profiles using seven degree of freedoms has been verified. The verification has been performed based on the results of the structural analysis of thin-walled bar systems which behavior under the external loading has been simulated using design schemes from thin shell finite elements. Structural analysis has been realized using software SCAD. The results of the performed investigation have pointed that the suggestion concerning «joint warping» existence or, in other words, the equal warping for the each end member cross-section sided to the joint under consideration often is not true even for those design cases, where plane design models with spatial application of the structural loading are considered. Only the shell finite-element model of the thin-walled bar system can describe the actual interaction of the thin-walled bars at the structural joint correctly.
Keywords: thin-walled bar, warping, bimoment, numerical simulation, finite element analysis, root-mean-square error.
