Abstract: In this article, possible geometric imperfections of equal angles are systematized and investigated, which affect the strength and bearing capacity of the belt of metal lattice towers of power transmission lines at the junction. The analysis of the degree of influence of factors of geometric imperfections for various types of bolted connection of the corners of the support chord is carried out. A numerical experiment was performed to calculate the dependence of the bearing capacity of the support chord corner in the butt joint on various factors.

Key words: overhead power line (OHL), metal support, bolted connection, regression analysis, factors of influence, significance coefficients of factors.
