Annotation: A new one-bolt compounds «INEKO», competitive with using a light coating of metals, have been suggested on the ground of analysis of existing technical solutions of node connections of space structures. Offered connection does not require expensive technology in production and can be made in the settings of plant of metal structures. The structure, having node connection of «INEKO», differs in high fabricability, because it contains only two nominal size: chord and brace element. The article presents the results of numerical and experimental researches of node connection of the new constructive form of structural coverage of the «INEKO». Numerical researches of stress-strain state of gusset plate of brace space structure were made with the use of «SCAD» software. The accepted structural design did not take into account pliability of gussets, chord and brace element. This calculation allowed to define theoretical sustaining capacity of gusset that determines character of work of all structure. Actual stress-strain state of gusset made on models of plate girder collected from elements of the «INEKO». Comparison of numeral and experimental researches allowed to take into account pliability of gussets at the real designing of structural coverage of «INEKO».
Keywords: supporting construction of coverage, space structure, actual sustaining capacity, calculation, recommendations.
