Stress-Strain State of an Anchor Angle Tower 220 kV with Imperfections under the Action of Static Loads
Abstract: The article analyzes the stress-strain state of the anchor angle tower of an overhead line (OL), which is considered as a spatial repeatedly statically indeterminate through system with hinged nodes. To compare the SSS indicators of the support elements, the schemes were analyzed when working with and without imperfections. In the first scheme, the operation of the structure was considered as “without defects”, in the second scheme, the formation of a general distortion of the lattice elements from the plane of the support face was modeled and the response of the system to elements with imperfections was analyzed. Based on the analysis of the operation of the system with imperfections, it was possible to identify the influence of rods with ultimate deformation on the work both with the elements adjacent to them (barrel, grate) and on the structure as the whole. Based on the results of the research, schemes for tensometric studies of the support U 220-2r+9 were determined.
Keywords: anchor angle tower, overhead power line, stress-strain state, numerical studies, distortion, imperfect structural behavior.
