This document gives guidelines and recommendations for the general principles of design appropriate to articles to be hot dip galvanized after fabrication (e.g. in accordance with ISO 1461) for the corrosion protection of, for example, articles that have been manufactured in accordance with EN 1090-2. This document does not apply to hot dip galvanized coatings applied to continuous wire or sheet (e.g. to EN 10346).

1.1 Scope of EN 1993-1-9 (1) EN 1993-1-9 gives design methods for the verification of the fatigue design situation of steel structures. NOTE Steel structures consist of members and their joints. Each member and joint can be represented as a constructional detail or as several of the latter. (2) Design methods other than the stress-based methods, such as the notch strain method or fracture mechanics methods, are not covered by EN 1993-1-9. (3) EN 1993-1-9 only applies to structures made of all grades of structural steels and products within the scope of EN 1993-1 (all parts), in accordance with the provisions noted in the detail category tables or annexes. (4) EN 1993-1-9 only applies to structures where execution conforms to EN 1090-2. NOTE Supplementary execution requirements are indicated in the detail category tables.

(3) The design methods of EN 1993-1-9 are generally derived from fatigue tests on constructional details 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).

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.
