Multi-face Metal Columns for Urban Structures

The article considers national and foreign experience of the use of multi-face bent metal columns (tubes) for the erection of tower structures for the needs of modern cities. The authors present a review of the literature concerned and try to reveal the problem trends in the field for the purpose of the further study of stress-and-strain state (SSS) of the aforesaid structural elements as well as the special features of their work under load. This study may improve the structural shape of the aforesaid multi-face metal structures, improve their design as well as the consideration of the wind load contributing much to their stress-and-strain state. The authors also consider the prospects of production and use of multi-face metal structural elements in modern construction in Russia. The special features of the design methods concerned and a comparative analysis of the SSS parameters of multi-face bent metal columns are considered, too.
