Annotation: This paper shows the need to take into account the survivability of the structure using the example of the anchor-angular support U220-2+9 overhead line (overhead line), which is considered as a spatial repeatedly statically indeterminate through system. To compare the survivability indicators, supports were modeled with the formation of a general curvature of the lattice elements from the plane of the support face to the compressed and stretched elements alternately, the response of the system to elements with imperfections was analyzed. The calculation is performed in the author’s software package, which is implemented in the MATLAB programming language with the ability to transfer data to the system for automated calculation of CAD LIRA by means of an output text file. Based on the analysis of the operation of the system with imperfections, it was possible to identify the order of failure of their elements, a group of the most important elements that determine the reliability of the system as a whole.
Keywords: anchor-angular support, overhead power line, stress-strain state, reliability calculation, survi-vability, numerical studies, operation of structures with imperfections.
