The study of the influence of initial mast shaft imperfections on the values of internal forces and the effort of mast structure

This paper describes the results of static-strength calculations of a real mast taking into account the initial imperfections in the form of initial mast span curves. The primary objective of the study was to examine to what extent the initial mast shaft imperfections influence the effort of structure elements of the mast. The remarks and conclusions are of practical importance and can be used in the design of guyed lattice masts.
