The issues of designing structures from thin-walled profiles with nodal joints on bolts are considered, a method of strength calculation is developed. The calculation takes into account two variants of bolted joints on high-strength bolts and unregulated tightening connections, two variants of the operation of a shear-resistant connection with a “breakdown” when overcoming the force over the friction force of the contact surfaces and without a “breakdown”. The methodology includes the bolted connection splitting for the elements working in tension and compression.
