Title of the articleThe central node of the upper belt truss from rods cold-formed profile
Abstract.Problem statement. When designing trusses from cold-formed profiles, bolting is used in the nodes connecting its elements with sheet gussets. This connection of the central node of the upper belt leads to a decrease in its strength, rigidity out of the plane. The existing solutions have drawn conclusions about these nodal joints, namely, their strength, deformability and reinforcement are shown, which is rational when designing trusses from thin-walled cold-formed elements. Results. The main results of the research consist in the development of a constructive solution to the joint node and the determination of its stress-strain state as calculated in the «Solidworks» software package. Conclusions. The significance of the research results for the construction industry is that the calculations made will allow to judge the work of the connected elements of the upper belt. The proposed design of the gusset can be used in the manufacture of roof trusses of the coating.
Keywords.the stress-strain state, the truss node, in the truss connection fasone, thin profile, truss coverage.
