(3) This Part does not give guidance on specialist aspects of snow loading, for example:
-   impact snow loads resulting from snow sliding off or falling from a higher roof;
-   changes in shape or size of the construction works due to the presence of snow or the accretion of ice which could affect the wind action;
-   loads in areas where snow is present all year round;

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.
(3) Methods are also given for stressed-skin design, using steel sheeting as a structural diaphragm.
(4) This document does not apply to cold-formed circular and rectangular structural hollow sections supplied to EN 10219, for which reference is made to EN 1993 1 1 and EN 1993 1 8.
(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.
1.2   Assumptions
(1) Unless specifically stated, EN 1990, EN 1991 (all parts) and EN 1993 1 1 apply.
(2) The design methods given in prEN 1993 1 3 are applicable if:
-   the execution quality is as specified in EN 1090 4, the execution quality of bolted connections is as specified in EN 1090 2, and
-   the construction materials and products are as specified in the relevant parts of EN 1993 (all parts), or in the relevant material and product specifications.
(2) EN 1993 is intended to be used in conjunction with:
-   the parts of EN 1992 to EN 1999 where steel structures or steel components are referred to within those documents;
-   EN, EAD and ETA standards for construction products relevant to steel structures.

Eurocode 3 - Design of steel structures - Part 1-13: Beams with large web openings
SIST EN 1993-1-13:2024

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.
