Execution of steel structures and aluminium structures – Part 2: Technical requirements for steel structures

This European Standard specifies requirements for execution of structural steelwork produced from:
a)   hot rolled, structural steel products up to S690;
b)   cold formed components and sheeting up to S700MC for stainless steels and S690 for structural steels;
c)   hot finished and cold formed austenitic and austenitic-ferritic stainless steel products;
d)   circular, square or rectangular hollow sections, produced as a standard range of rolled steel shapes or custom-made fabricated shapes.
This European Standard may be used for structural steel grades up to S960, provided that conditions for execution are verified against reliability criteria and any necessary additional requirements are specified.
This European Standard specifies requirements independent of the type and shape of the steel structure (e.g. buildings, bridges, plated or latticed components...). It specifies execution classes linked with consequence classes and with the production and service categories. Its scope includes structures subjected to fatigue.
NOTE 1   Consequence classes are defined in EN 1990, Annex B.
NOTE 2   Annex B of this European Standard gives guidelines for the choice of execution class
This European Standard applies to structures designed according to the relevant part of EN 1993. For cold formed components and sheeting, the requirements of this European Standard apply to construction classes I and II as defined in EN 1993-1-3.
NOTE 3   Requirements for execution of sheeting in construction class III may be specified in national rules.
This European Standard applies to steel components in composite steel and concrete structures designed according to the relevant part of EN 1994.
This European Standard may be used for structures designed according to other design rules provided that conditions for execution comply with them and any necessary additional requirements are specified.
This European Standard gives requirements for surfaces prior to the application of a protective treatm

Ausführung von Stahltragwerken und Aluminiumtragwerken - Teil 2:Technische Anforderungen an Tragwerke aus Stahl

Diese Europäische Norm legt Anforderungen an die Ausführung von Stahltragwerken fest, die hergestellt sind aus:
-   warmgewalzten Baustahlerzeugnissen bis zu S690;
-   kaltgeformten Bauteilen und dünnwandigen Profilblechen bis zu S700MC bei nichtrostenden Stählen und S690 bei Baustählen;
-   warmgeformten und kaltgeformten austenitischen und austenitisch-ferritischen nichtrostenden Stahlerzeugnissen;
-   kreisförmigen, quadratischen oder rechteckigen Hohlprofilen, hergestellt als standardisierte Walzstahlerzeugnisse oder als sondergefertigte Erzeugnisse.
Diese Europäische Norm kann für Baustahlsorten bis zu S960 angewendet werden, unter der Voraussetzung, dass die Ausführungsbedingungen in Hinblick auf die Zuverlässigkeitskriterien nachgewiesen sind und alle notwendigen Zusatzanforderungen festgelegt sind.
Diese Europäische Norm legt Anforderungen unabhängig von der Art und Gestalt des Stahltragwerks fest (z. B. Hochbau, Brücken, Flächentragwerke oder Fachwerke ...). Es werden Ausführungsklassen festgelegt, die mit Schadensfolgeklassen und mit Herstellungs- und Nutzungskategorien verknüpft sind. Der Anwendungsbereich schließt ermüdungsbeanspruchte Tragwerke ein.
ANMERKUNG 1   Schadensfolgeklassen sind festgelegt in EN 1990, Anhang B.
ANMERKUNG 2   Anhang B dieser Europäischen Norm enthält Hinweise für die Wahl der Ausführungsklasse
Diese Europäische Norm gilt für Tragwerke, die nach dem entsprechenden Teil von EN 1993 bemessen wurden. Für kaltgeformte Bauteile und dünnwandige Profilbleche gelten die Anforderungen dieser Europäischen Norm für die Tragwerksklassen I und II nach EN 1993-1-3.
ANMERKUNG 3   Anforderungen an die Ausführung von dünnwandigen Blechen in der Tragwerksklasse III können in nationalen Regelwerken festgelegt werden.
Diese Europäische Norm gilt für Bauteile in Verbundbauweise aus Stahl und Beton, bei denen das Tragwerk nach dem entsprechenden Teil von EN 1994 bemessen wurde.

Exécution des structures en acier et des structures en aluminium – Partie 2: Exigences techniques pour les structures en acier

La présente Norme européenne spécifie des exigences pour l'exécution des charpentes en acier considérées en tant que structures ou éléments de structure fabriqués à partir de :
-   produits en acier de construction, laminés à chaud jusqu'à la nuance S690 incluse ;
-   éléments et plaques formés à froid jusqu'à la nuance S700 incluse pour les aciers inoxydables et S690 pour les aciers au carbone ;
-   produits en acier inoxydable, austénitique, austéno-ferritique et ferritique, finis à chaud et formés à froid ;
-   profils creux finis à chaud et formés à froid, y compris produits d'une gamme normalisée, produits laminés fabriqués à la demande et profils creux fabriqués par soudage.
La présente Norme européenne peut être utilisée également pour les nuances d'acier de construction jusqu'à S960 incluse, sous réserve que les conditions d'exécution soient vérifiées en regard des critères de fiabilité et que toutes les exigences supplémentaires nécessaires soient spécifiées.
La présente Norme européenne fixe des exigences indépendamment du type et de la forme de la structure en acier (par exemple, bâtiments, ponts, éléments en plaques ou en treillis, ...), y compris les structures soumises à la fatigue ou à des actions sismiques. Ces exigences sont exprimées en termes de classes d’exécution.
La présente Norme européenne s'applique aux structures calculées selon la partie appropriée de l'EN 1993.
La présente Norme européenne s'applique aux éléments et plaques structuraux tels que définis dans l'EN 1993-1-3.
La présente Norme européenne s'applique aux éléments en acier utilisés dans les structures mixtes acier béton calculées selon la partie appropriée de l'EN 1994.
La présente Norme européenne peut être utilisée pour des structures calculées selon d'autres règles de calcul, sous réserve que les conditions d'exécution soient conformes à ces règles et que toutes les exigences supplémentaires nécessaires soient spécifiées.
