Theoretical foundations of calculated dependencies for welded nodes of tubular structures

The calculation dependencies used in the modern methodology for calculating the welded nodes of steel tubular structures are presented and considered, the features of the nodes, the calculated models accepted when calculating the nodes, the exhaustion of the strength and stability of belts and braces, as well as their thin walls are shown. The difference between the modern methodology for calculating nodes and calculation dependencies adopted in the current standard of the European Union EN 1993-1-8 (2005) “Compounds of Elements of Steel structures”, which is planned to be adopted in the new edition of the Eurocode 3 in 2020, which will include the latest changes in the methodology calculations given in monographs.
The monograph is intended for bachelors and undergraduates of construction universities and faculties studying in the areas of Construction, graduate students in the direction of Technology and construction technology, scientists, engineers, as well as specialists in the field of technical regulation
