Eurocode 3: Design of steel structures - Part 1-9: Fatigue

Eurocode 3: Design of steel structures - Part 1-9: Fatigue

(1) EN 1993-1-9 gives methods for the assessment of fatigue resistance of members, connections and joints subjected to fatigue loading.
(2) These methods are derived from fatigue tests with large scale specimens, that include effects of geometrical and structural imperfections from material production and execution (e.g. the effects of tolerances and residual stresses from welding).
NOTE 1 For tolerances see EN 1090. The choice of the execution standard may be given in the National Annex, until such time as EN 1090 is published.
NOTE 2 The National Annex may give supplementary information on inspection requirements during fabrication.
(3) The rules are applicable to structures where execution conforms with EN 1090.
NOTE Where appropriate, supplementary requirements are indicated in the detail category tables.
(4) The assessment methods given in this part are applicable to all grades of structural steels, stainless steels and unprotected weathering steels except where noted otherwise in the detail category tables. This part only applies to materials which conform to the toughness requirements of EN 1993-1-10.
(5) Fatigue assessment methods other than the R-N methods as the notch strain method or fracture mechanics methods are not covered by this part.
(6) Post fabrication treatments to improve the fatigue strength other than stress relief are not covered in this part.
(7) The fatigue strengths given in this part apply to structures operating under normal atmospheric conditions and with sufficient corrosion protection and regular maintenance. The effect of seawater corrosion is not covered. Microstructural damage from high temperature (> 150 °C) is not covered.

1.1   Scope of prEN 1993-1-3
(1) This document provides rules for structural design of cold-formed steel members and sheeting.
(2) This document applies to cold-formed steel products made from coated or uncoated hot- or cold-rolled sheet or strip, which have been cold-formed by processes such as roll-forming or press braking. It also covers sheeting and members which are curved during fabrication by continuous bending or roll-forming. Sheeting which has the curvature created by crushing the inner flanges is not included. This document is also applicable to the design of profiled steel sheeting for composite steel and concrete slabs at the construction stage, see EN 1994. The execution of steel structures made of cold-formed steel members and sheeting is covered in EN 1090 4. Provisions for bolted connections are provided in EN 1090 2.
NOTE   The rules in prEN 1993 1 3 complement the rules in other parts of EN 1993 1.

(5) This document provides methods for design by calculation and for design assisted by testing. The methods for design by calculation apply only within the stated ranges of material properties and geometric proportions, for which sufficient experience and test evidence is available. These limitations do not apply to design assisted by testing.

(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.

Eurocode 3 - Design of steel structures - Part 1-13: Beams with large web openings
kSIST FprEN 1993-1-13:2023

1.1   Scope of EN 1993-1-13
1.1.1   General
(1) This document gives supplementary provisions that extend the application of EN 1993-1-1 and EN 1993-1-5 to the design of rolled and welded steel sections with various shapes of web openings. The following cases are considered:
-   rolled or welded beams with single or widely spaced web openings;
-   rolled or welded beams with closely spaced web openings;
-   cellular beams with circular openings made by cutting and re-welding two parts of steel sections that may be different in dimensions;
-   beams with hexagonal and sinusoidal openings made by cutting and re-welding two parts of steel sections that may be different in dimensions.
(2) This document applies to uniform members with I or H profiles, which are symmetric about the weak axis. It does not apply to non-prismatic or curved beams although the same principles can apply.
(3) This document applies to steel beams with web openings that are subjected to sagging (positive) or to hogging (negative) bending moments.
(4) This document covers the verification of the resistance at the openings and their effects on the global behaviour of the beam, including lateral torsional buckling.
(5) Alternative methods are presented for beams with circular openings and with sinusoidal openings in which the forces and resistances are calculated by increments around or along the openings and which are suitable for computer methods.
(6) This document applies to web slenderness, hw/tw, not exceeding 121ε. The local checks at and between adjacent openings apply to web slenderness up to this limit. The material parameter ε is defined in EN 1993-1-1:2022, 5.2.5 (2).
NOTE   The limit of 121ε is the limit of a Class 4 web for a steel section with equal flanges. It is used as a convenient limit for the application of this document, including mono-symmetric sections.
(7) This document does not cover fatigue. In case of fatigue, EN 1993-1-9 applies.
(8) This document does not cover fire design. For the design in case of fire, EN 1993-1-2 applies.
(9) This document does not cover the buckling verification of members with web openings under axial force.
1.1.2   Shapes of web openings
(1) The different shapes of web openings that are considered in this document are shown in Figure 1.1.
Figure 1.1 - Different shapes of web openings in steel beams
1.1.3   Stiffened openings
(1) This document also covers openings in the web of beams that are reinforced by longitudinal stiffeners and/or transverse stiffeners on one or both sides of the web, see Figure 1.2.
NOTE   The National Annex can give rules for alternative types of stiffener.
Figure 1.2 - Stiffening of openings in beam webs
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 1993-1-13 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 and product specifications.
