Annotation: On the basis of the analysis of existing technical solutions of nodal joints of structural coatings, a new single-bolt joint «INEKO» is proposed, which is competitive when used in light metal coatings. The proposed connection does not require expensive manufacturing technologies, but can be manufactured under the conditions of a metalwork plant. The structure with the INEKO nodal connection is distinguished by its high manufacturability, since it contains only two standard sizes: a belt and a diagonal element. The article presents the results of numerical and experimental studies of the nodal connection of the new structural form of the structural coating «INEKO». Numerical studies of the stress-strain state (SSS) of the brace gusset and flat girder of structural elements were performed using the SCAD software package. The accepted design scheme did not take into account the flexibility of the nodal gussets of the belt and diagonal elements. This calculation made it possible to determine the theoretical bearing capacity of the nodal gusset plate, which determines the nature of the operation of the entire structure. The actual VAT of the gusset was investigated in the course of field tests of a flat truss and assembled from «INEKO» structure elements. Comparison of numerical and experimental studies made it possible to take into account the malleability of nodal gussets in the actual design of «INEKO» structural coatings.
Keywords: bearing structures of the coating, structure, actual bearing capacity, calculation, recommendations.
