1.1 Scope of FprEN 1993-1-8 (1) FprEN 1993-1-8 provides rules for structural design of joints subject to predominantly static loading using all steel grades from S235 up to and including S700, unless otherwise stated in individual clauses. NOTE As an alternative to the design rules provided in Clause 9, the design rules given in CEN/TR 1993-1-801 "Eurocode 3: Design of steel structures - Part 1 801: Hollow section joints design according to the component method" can be used. (2) The provisions in this document apply to steels complying with the requirements given in EN 1993 1 1 and to material thickness greater than or equal to 3 mm, unless otherwise stated in individual clauses. 1.2 Assumptions (1) Unless specifically stated, EN 1990, EN 1991 (all parts) and the other relevant parts of EN 1993-1 (all parts) apply. (2) The design methods given in FprEN 1993-1-8 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 EN 1993 (all parts), or in the relevant material and product specifications.

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 1993-1-10 (1) EN 1993-1-10 specifies rules for the selection of steel grades and qualities related to fracture toughness to avoid brittle fracture. NOTE Steel quality is also known as (Charpy) subgrade. (2) EN 1993-1-10 specifies rules to specify through thickness properties for welded elements to reduce the risk of lamellar tearing. (3) EN 1993-1-10 specifies additional toughness requirements for specific cases to ensure upper shelf toughness in relation to design ultimate resistance in tension and seismic design. (4) EN 1993-1-10 specifies rules for structural steels as listed in EN 1993-1-1. This document applies to steel grades S235 to S700. (5) EN 1993-1-10 specifies rules that apply to the selection of parent material only. (6) EN 1993-1-10 specifies rules that apply to steel materials covered by EN 1993-1-1:2022, 5.1(3), provided that each individual piece of steel is tested in accordance with the requirements of EN 1993 1 1:2022, 5.2.1 and EN 1090-2:2018+A1:2024, 5.1. (7) This document does not apply to material salvaged from existing steelwork subjected to fatigue or fire. 1.2 Assumptions (1) Unless specifically stated, EN 1990, EN 1991 (all parts) and the other relevant parts of EN 1993-1 (all parts) apply. (2) The design methods given in EN 1993-1-10 are applicable if: - the execution quality is as specified in EN 1090-2 or EN 1090-4, and - the construction materials and products used are as specified in the relevant parts of EN 1993 (all parts), or in the relevant material and product specifications.

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. (5) EN 1993-1-9 applies to structures operating under normal atmospheric conditions and with sufficient corrosion protection and regular maintenance. The effect of seawater corrosion is not covered. (6) EN 1993-1-9 applies to structures with hot dip galvanizing in accordance with the provisions noted in the detail category tables or annexes. (7) Microstructural damage from high temperature (> 150°C) that occurs during the design service life is not covered. (8) EN 1993-1-9 gives guidance of how to consider post-fabrication treatments that are intended to improve the fatigue resistance of constructional details. 1.2 Assumptions (1) Unless specifically stated, EN 1990, EN 1991 (all parts) and EN 1993 1 (all parts) apply. (2) The design methods given in EN 1993-1-9 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 on EN 1993 (all parts), or in the relevant material and product specifications. (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).
