Eurocode 3 - Design of steel structures - Part 4-2: Tanks; German and English version FprEN 1993-4-2:2025
Abstract
(1) EN 1993-4-2 provides rules for structural design of vertical cylindrical, conical and pedestal above-ground steel tanks for the storage of liquids and refrigerated liquified gas products. (2) This document is applicable to the design for resistance of cylindrical walls and flat bottoms constructed using unstiffened plates. The design of conical and dome roofs as shell structures (unsupported) or as supported on a structural framework (supported) are also covered. (3) This document is only applicable to the requirements for resistance and structural stability of steel tanks. NOTE Further guidance on design aspects other than the structural design can be obtained from the documents EN 14015 or EN 14620 (all parts), as applicable. (4) This document only covers steel tank structures in Tank Groups 1, 2 and 3, as defined in this document. NOTE Tank Group 4 is not defined in this document (see 3.1.41). (5) This document is applicable to tanks within the following dimensional limits (see EN 1991-4): − Tank aspect ratio hS/d < 10 − Tank total height hS < 70 m − Tank diameter d < 100 m (6) This document includes suitable rules for the design of tanks intended to store solids suspended in a liquid, where the appropriate global density of the mixture is used. NOTE Tanks used for the separation of mineral particles of different density fall into this category. (7) This document does not apply to the following: a) tanks with gross capacity less than 5 m3 (5 000 l); b) dished-end tanks that have a diameter less than 5 m; c) tanks with characteristic internal pressures above the liquid surface greater than 50 kPa (500 mbar) (see pressure equipment directive); d) design metal temperatures outside the ranges defined in Clause 5, e) tanks of rectangular and other non-circular planforms; f) tanks exposed to fire; g) floating roofs and floating covers; h) ancillary structures such as stairways, platforms, nozzles, piping and access doors. (8) This document does not cover a) the special requirements for seismic design of tanks, b) the design of a supporting structure, c) the design of ancillary structures such as stairways, platforms, pipe racks and ladders, d) the design of an aluminium roof structure on a steel tank, e) reinforced concrete foundations for steel tanks, f) the design of a conical hopper, g) the design of a transition junction between the base of a cylindrical shell wall and a conical hopper, h) the design of a supporting ring girder in an elevated tank.
