Eurocode 3 - Design of steel structures - Part 3: Towers, masts and chimneys

This document provides rules for structural design of towers, masts and chimney structures, that fall into any of the following classifications, with the exceptions given in (3), (4) and (5). This document is applicable to: a) self-supporting towers and guyed masts with or without attachments. The shafts of towers and masts can be of lattice type or of circular or polygonal cross-section. b) chimney structures of circular cross-section that are cantilevered, supported at intermediate levels or guyed. This document does not apply to: a) polygonal and circular lighting columns covered by the EN 40 series; b) wind turbine towers (see the EN 61400 series). This document does not cover special provisions for seismic design, which are given in the EN 1998 series. Special measures that might be necessary to limit the consequences of accidents are not covered in this document. For resistance to fire, see EN 1993-1-2. Provisions for the guys of guyed structures are given in EN 1993-1-11 and supplemented in this document. For provisions concerning aspects such as chemical attack, thermo-dynamical performance or thermal insulation of chimneys see EN 13084-1. For the design of liners see EN 13084-6.
