Abstract
The article presents the results of the analysis of the stress-strain state of the developed jointing node of construction scaffolding (spatial rod temporary structures), since nodal connections are often the weakest elements of such temporary structures. The analysis of the stress-strain state of the node was performed on the basis of a full-scale experiment. The study revealed the most stressed zones in the node structure, as well as the causes of node destruction. Nodes are well known to be the weakest elements of scaffolding. It often happens that structural elements are more stable than the connections between them. Mobile spatial rod structures are very popular in construction at the present time. These structures are used for the construction of ski jumps, stands, stages and scaffolding. They are also used as support scaffolding to support the formwork of floorings. Therefore, the development of new nodal solutions, increasing the bearing capacity of nodal joints and studying their stress-strain state under various loads is a very important task.
