Abstract: The results of field surveys of metal chimneys are presented in the article. The basic geometric imperfections metal chimney’s shells are revealed. Systematization of the data of geometric imperfections is performed and their frequency is determined. For the laboratory research on determining effects of the local dimple on the stress-strain state of metal chimney’s shells the equivalent wind load was identified and substantiated. A laboratory setting for studying the influence of local dimple on the stress-stain state of shells metal chimneys were designed and manufactured on the basis of numerical studies. The sequence of a laboratory experiment is determined.

Keywords: steel chimney, geometrical imperfections, equivalent, local stresses, scale model, the stress concentration.

Pages: 163-172.
