Eurocode 3 - Design of steel structures - Part 1-5: Plated structural elements

Edition date: 2026-10-01
In Force
Available languages: German, English
Summary: 1.1 Scope of EN 1993-1-5 (1) This document provides rules for structural design of stiffened and unstiffened nominally flat plates which are subject to in-plane forces. (2) Non-uniform stress distributions due to shear lag, in-plane load introduction and plate buckling are covered. The effects of out-of-plane loading are outside the scope of this document. NOTE 1 The rules in this part complement the rules for class 1, 2, 3 and 4 sections, see EN 1993-1-1. NOTE 2 For the design of slender plates which are subject to repeated direct stress and/or shear and also fatigue due to out-of-plane bending of plate elements ("breathing"), see EN 1993-2 and EN 1993-6. NOTE 3 For the effects of out-of-plane loading and for the combination of in-plane effects and out-of-plane loading effects, see EN 1993-2 and EN 1993-1-7. (3) Single plate elements are considered as nominally flat where the curvature radius r in the direction perpendicular to the compression satisfies, as illustrated in Figure 1.1: r≥b^2/t (1.1) where b is the panel width; t is the plate thickness. Figure 1.1 - Definition of plate curvature 1.2 Assumptions (1) Unless specifically stated, EN 1990, the EN 1991 series and EN 1993-1-1 apply. (2) The design methods given in EN 1993-1-5 are applicable if - the execution quality is as specified in EN 1090-2 and - the construction materials and products used are as specified in the relevant parts of the EN 1993 series or in the relevant material product specifications.

1.1 Domaine d'application de l’EN 1993-1-5 (1) Le présent document fournit les règles de calcul structural pour des plaques nominalement plates, raidies et non raidies, qui sont soumises à des charges dans le plan. (2) Les répartitions non uniformes de contrainte dues au traînage de cisaillement, à l'application de charges dans le plan et au voilement des plaques sont couvertes. Les effets des charges hors du plan ne sont pas traités. NOTE 1 Les règles définies dans la présente partie complètent les règles applicables aux sections de classe 1, 2, 3 et 4, voir l'EN 1993-1-1. NOTE 2 Pour le calcul des plaques élancées sur lesquelles s'exercent des contraintes normales et/ou de cisaillement répétées et qui sont soumises à la fatigue due à la flexion hors plan de leurs éléments constitutifs (respiration), voir l'EN 1993-2 et l'EN 1993-6. NOTE 3 Pour les effets des charges exercées hors du plan et pour la combinaison des effets desdites charges et des charges exercées dans le plan, voir l'EN 1993-2 et l'EN 1993-1-7. (3) Les plaques simples peuvent être considérées comme planes lorsque le rayon de courbure r, dans le sens perpendiculaire à la compression, satisfait (voir la Figure 1) : [...]

1.1 Anwendungsbereich von EN 1993 1 5 (1) Dieses Dokument enthält Regelungen für die Tragwerksplanung von nominell ebenen und in ihrer Ebene belasteten Blechen mit oder ohne Steifen. (2) Ungleichmäßige Spannungsverteilungen infolge Schubverzerrungen, Lasteinleitung in der Ebene sowie Plattenbeulen sind abgedeckt. Die Wirkungen von Lasten quer zur Bauteilebene werden in diesem Dokument nicht behandelt. ANMERKUNG 1 Die Regelungen in diesem Teil ergänzen die Regelungen für Querschnitte der Querschnittsklassen 1, 2, 3 und 4, siehe EN 1993 1 1. ANMERKUNG 2 Regelungen zu schlanken Blechen mit wechselnden Längsspannungen und/oder Schubspannungen, die zu Ermüdung durch wechselnde Biegung aus der Blechebene („Blechatmen“) führen können, sind in EN 1993 2 und EN 1993 6 angegeben. ANMERKUNG 3 Regelungen zur Wirkung von Lasten quer zur Blechebene und zur Kombination von Lastwirkungen in der Ebene und aus der Ebene sind EN 1993 2 und EN 1993 1 7 zu entnehmen. (3) Einzelne Beulfelder werden als nominell eben angesehen, wenn für den Krümmungsradius r in der Richtung senkrecht zur Druckrichtung entsprechend der Darstellung in Bild 1.1 gilt: r≥b^2/t (1.1) Dabei ist b die Blechbreite; t die Blechdicke. Bild 1.1 — Definition der Blechkrümmung 1.2 Annahmen (1) Sofern nicht spezifisch angegeben, gelten EN 1990, die Normenreihe EN 1991 und EN 1993 1 1. (2) Die in EN 1993 1 5 angegebenen Bemessungsverfahren sind anwendbar, wenn — die Qualität der Ausführung den Festlegungen nach EN 1090 2 entspricht; und — die verwendeten Baustoffe und Produkte den Festlegungen nach den maßgebenden Teilen der Normenreihe EN 1993 oder nach den maßgebenden Baustoffproduktspezifikationen entsprechen.
