Eurocode 3 - Design of steel structures - Part 1-5: Plated structural elements
(1) EN 1993-1-5 gives design requirements of stiffened and unstiffened plates which are subject to inplane
forces.
(2) Effects due to shear lag, in-plane load introduction and plate buckling for I-section girders and box
girders are covered. Also covered are plated structural components subject to in-plane loads as in tanks and
silos. 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.
NOTE 4: Single plate elements may be considered as flat where the curvature radius r satisfies:
t
a
r
2
3 (1.1)
where a is the panel width
t is the plate thickness
Eurocode 3 - Bemessung und Konstruktion von Stahlbauten - Teil 1-5: Plattenförmige Bauteile
(1) EN 1993 1 5 enthält Regelungen für den Entwurf und die Berechnung von aus ebenen Blechen zusammengesetzten und in ihrer Ebene belasteten Bauteilen mit oder ohne Steifen.
(2) Diese Regelungen gelten für Blechträger mit I Querschnitt und Kastenträger, bei denen ungleichmäßige Spannungsverteilungen infolge Schubverzerrungen sowie Beulen unter Längsspannungen, Schub¬span¬nungen und Querlasten auftreten. Sie gelten auch für ebene Bleche aller anderen Bauteile, z. B. von Tankbauwerken und Silos, soweit Lasten und Beanspruchungen in der Ebene der Bauteile wirken. Die Wirkungen von Lasten quer zur Bauteilebene werden in EN 1993 1 5 nicht behandelt.
ANMERKUNG 1 Die Regelungen in EN 1993 1 5 ergänzen die Regelungen für Querschnitte der Querschnittsklassen 1, 2, 3 und 4, siehe EN 1993 1 1.
ANMERKUNG 2 Regelungen zu schlanken Platten mit wechselnden Längsspannungen und/oder Schubspannungen, die zu Ermüdung durch wechselnde Biegung aus der Plattenebene (Blechatmen) führen können, sind in EN 1993 2 und EN 1993 6 angegeben.
ANMERKUNG 3 Regelungen zur Wirkung von Lasten quer zur Plattenebene und zur Kombination von Lastwirkungen in der Ebene und aus der Ebene sind EN 1993 2 und EN 1993 1 7 zu entnehmen.
ANMERKUNG 4 Einzelne Blechfelder dürfen als eben angesehen werden, wenn für den Krümmungsradius r gilt:
(1.1)
Dabei ist
a die Blechfeldbreite;
t die Blechdicke.
Eurocode 3 - Calcul des structures en acier - Partie 1-5: Plaques planes
(1) L'EN 1993-1-5 spécifie les exigences de calcul relatives aux plaques raidies et non raidies soumises a des charges dans le plan.
(2) Les effets du traînage de cisaillement, de l'application de charges dans le plan et du voilement des plaques pour les poutres en I a âme pleine et les poutres-caissons sont couverts. Les plaques planes soumises a des charges dans le plan telles que celles exercées dans les réservoirs et les silos, sont également couvertes. Les effets des charges hors du plan ne sont pas traités.
NOTE 1 Les regles définies dans la présente partie completent les regles applicables aux sections de classe 1, 2, 3 et 4 , voir EN 1993-1-1.
NOTE 2 Pour les plaques élancées sur lesquelles s'exercent des contraintes normales et/ou de cisaillement répétées et qui sont soumises a la fatigue due a la flexion hors plan de leurs éléments constitutifs (respiration), voir EN 1993-2 et 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 EN 1993-2 et EN 1993-1-7.
NOTE 4 Les plaques simples peuvent etre considérées comme planes lorsque le rayon de courbure r satisfait :
(1.1)
ou
a est la largeur du panneau ;
t est l'épaisseur de la plaque.
Evrokod 3: Projektiranje jeklenih konstrukcij - 1-5. del: Elementi pločevinaste konstrukcije
(1) Standard EN 1993-1-5 podaja zahteve za projektiranje utrjenih ali neutrjenih plošč, ki so podvržene silam v ravnini.
(2) Zajeti so učinki zaradi strižne podajnosti, nastanka obtežbe v ravnini in upogibanja plošče za I-nosilce in škatlaste nosilce. Zajeti so tudi prevlečeni sestavni deli konstrukcij, ki so podvrženi obtežbam v ravnini, kot so rezervoarji in silosi. Učinki obtežb zunaj ravnine niso zajeti v tem dokumentu.
OPOMBA 1: Pravila v tem delu dopolnjujejo pravila za prereze razreda 1, 2, 3 in 4, glej standard EN 1993-1-1.
OPOMBA 2: Za projektiranje vitkih plošč, ki so podvržene ponavljajočim se neposrednim napetostim in/ali strižnim napetostim in tudi utrujenosti zaradi upogibanja ploščatih elementov zunaj ravnine (dihanje), glej standarda EN 1993-2 in EN 1993-6.
OPOMBA 3: Za učinke obtežb zunaj ravnine in za kombinacijo učinkov v ravnini in učinkov obtežb zunaj ravnine glejte standarda EN 1993-2 in EN 1993-1-7.
OPOMBA 4: Posamezni ploščati elementi se lahko štejejo za ravne, ko polmer ukrivljenosti r izpolnjuje:
tar23 (1.1), pri čemer je a širina plošče, t je debelina plošče
