Development of nodal solutions for fixing cable ties in spatial rod structures

Abstract

Abstract The article presents the results of analysis of the stress-strain state of the developed new nodal solutions for fixing cable ties in collapsible spatially strained structures, since the existing nodal solutions are not intended for connecting cable ties. During operation under extreme conditions for the structure (sudden gusts of wind, dynamic effects), it is necessary to ensure the reliability of the nodal connections of the cable ties with the struts. It is also important to maintain the speed of building structures. The mentioned ideas influence on additional moments that worsen the work of the temporary structures node. Stress-strain state analysis of the original and newly developed node was performed on the basis of both computer modeling and natural experiment, the results were compared. In the course of the conducted research, the most stressed zones in the created nodes were identified, as well as the reasons for the destruction of newly created nodes.
