Eurocode 3 - Design of steel structures - Part 1-6: Strength and stability of shell structures

Edition date: 2025-05-28
In Force
Available languages: German, English
Summary: 1.1 Scope (1) EN 1993-1-6 provides rules for the structural design of plated steel structures that have the form of a shell of revolution (axisymmetric shell). (2) This document is applicable to unstiffened fabricated axisymmetric shells formed from isotropic rolled plates using both algebraic and computational procedures, and to stiffened axisymmetric shells with different wall constructions using computational procedures. It also applies to associated circular or annular plates and to beam section rings and stringer stiffeners where they form part of the complete shell structure. The general computational procedures are applicable to all shell forms. (3) This document does not apply to manufactured shells or to shell panels or to elliptical shell forms, except that its computational procedures are applicable to all shell structures. This document does not apply to structures under seismic or other dynamic loading. It does not cover the aspects of leakage of stored liquids or solids. (4) Cylindrical and conical panels are not explicitly covered by this document. However, the provisions of 9.8 can be used provided that appropriate boundary conditions are taken into account. (5) This document defines the characteristic and design values of the resistance of the structure. (6) This document is concerned with the requirements for design against the ultimate limit states of: — plastic failure; — cyclic plasticity; — buckling; — fatigue. (7) Overall equilibrium of the structure (sliding, uplifting, overturning) is not included in this document. Special considerations for specific applications are included in the relevant application parts of EN 1993. (8) Detailed formulae for the simple calculation of unstiffened cylinders, cones and spherical domes are given in the Annexes. (9) Provisions for simple calculations on specific stiffened shell types are given in EN 1993-4-1. (10) This document is intended for application to steel shell structures. Where no standard exists for shell structures made of other metals, including high strength steels, the provisions of this document are applicable provided the appropriate material properties of the metal are taken into account. (11) The provisions of this document are intended to be applied within the temperature ranges defined in the relevant EN 1993 application parts. (12) Where no application part defines a different range, this document applies to structures within the following limits: — design metal temperatures lie within the range −50 °C to +100 °C, except when using the special provisions given in 5.1; — radius to thickness ratios (r/t) within the range 50 to 2 000; — manufactured circular hollow sections according to EN 10210 and EN 10219 are outside the scope of this document and are covered by EN 1993-1-1. However, if no other provisions are available, the rules of this document are useful for manufactured circular hollow sections. In particular, this document is applicable to the design of manufactured piles (see EN 1993-5) provided the imperfections and tolerance requirements of EN 1993-5 are adopted in place of those specified in this document, and where no other standard covers the specific pile geometry. NOTE 1 Experimental and theoretical data relating to manufactured circular hollow sections were not considered when this document was drafted. The application of this document to such structures therefore remains the responsibility of the user. NOTE 2 The stress design rules of this document can be rather conservative if applied to some geometries and loading conditions for relatively thick-walled shells. NOTE 3 Thinner shells than r/t = 2 000 can be treated using these provisions but the provisions have not been verified for such thin shells. NOTE 4 The maximum temperature is restricted so that the influence of creep can be ignored where high temperature creep effects are not covered by the relevant application part. [...]

1.1 Domaine d'application du l’EN 1993-1-6 (1) L’EN 1993-1-6 établit les règles de dimensionnement des structures en plaques d'acier ayant la forme d'une coque de révolution (coque axisymétrique). (2) Le présent document s'applique aux coques axisymétriques fabriquées non raidies, formées à partir de plaques laminées isotropes à l'aide de procédures algébriques et informatiques, ainsi qu'aux coques axisymétriques raidies présentant différentes constructions de parois, à l'aide de procédures informatiques. Il s'applique également aux plaques annulaires ou circulaires et aux poutres annulaires et raidisseurs verticaux associés lorsqu'ils font partie de la structure complète en coque. Les procédures informatiques générales s'appliquent à toutes les formes de coques. (3) Le présent document ne s'applique ni aux coques manufacturées, ni aux panneaux de coques, ni aux coques de forme elliptique, à l'exception du fait que ses procédures informatiques sont applicables à toutes les structures en coque. Le présent document ne s'applique pas aux structures soumises à des charges sismiques ou autres charges dynamiques. Il ne traite pas des aspects liés aux fuites de liquides ou solides stockés. (4) Les panneaux cylindriques et coniques ne sont pas explicitement couverts par le présent document. Cependant, les dispositions de 9.8 peuvent être utilisées sous réserve de prendre en compte les conditions aux limites appropriées. (5) Le présent document définit les valeurs caractéristiques et de calcul de la résistance de la structure. (6) Le présent document énonce les exigences pour le calcul aux états limites ultimes de : — rupture plastique ; — plasticité cyclique ; — voilement ; — fatigue. (7) L'équilibre global de la structure (glissement, soulèvement, renversement) ne figure pas dans le présent document. Des considérations particulières concernant des applications spécifiques figurent dans les parties applicatives appropriées de l'EN 1993. (8) Les formules détaillées pour le calcul simple des cylindres, cônes et dômes sphériques non raidis sont données en Annexes. (9) Les dispositions relatives aux calculs simples sur des types de coques raidies spécifiques sont données dans l'EN 1993-4-1. (10) Le présent document est destiné à être appliqué aux structures en coque en acier. En l'absence de norme applicable aux structures en coque constituées d'autres métaux, y compris d'aciers à haute résistance, les dispositions du présent document s'appliquent à condition de prendre en compte les propriétés de matériau appropriées du métal concerné. (11) Les dispositions du présent document sont destinées à être appliquées dans les plages de températures définies dans les parties applicatives appropriées de l'EN 1993. (12) Lorsqu'aucune partie applicative ne définit de plage différente, le présent document s'applique aux structures dans les limites suivantes : — les valeurs de calcul des températures du métal se situent dans la plage de −50 °C à +100 °C, sauf lorsque les dispositions particulières énoncées en 5.1 sont appliquées ; — les rapports rayon-épaisseur (r/t) se situent dans la plage de 50 à 2 000 ; [...]
