1.1 Scope of EN 1991-1-3 (1) EN 1991-1-3 gives principles and rules to determine the values of loads due to snow to be used for the structural design of buildings and civil engineering works. (2) This Part does not apply to sites at altitudes above 1500 m, unless otherwise specified. NOTE For rules for the treatment of snow loads for altitudes above 1500 m see 6.1. (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; - lateral loading due to snow creep (e.g. lateral loads exerted by drifts); - loads due to artificial snow. 1.2 Assumptions The assumptions given in FprEN 1990:2022, 1.2 apply to EN 1991-1-3.

1.1 Scope of EN 1991-1-9 (1) EN 1991-1-9 gives principles and rules to determine the values of loads due to atmospheric icing to be used for following types of structures: - masts, - towers, - antennas and antenna structures, - cables, stays, guy ropes, etc., - rope ways (cable railways), - structures for ski-lifts, - buildings or parts of them exposed to potential icing, - towers for special types of construction such as for example transmission lines and wind turbines. NOTE Atmospheric icing on electrical overhead lines is covered by EN 50341-1. (2) EN 1991-1-9 specifies values for: - dimensions and weight of accreted ice, - shapes of accreted ice. (3) EN 1991-1-9 cover types of icing, ice loads acting on structures, and falling ice considerations. NOTE Wind actions on iced structures are covered by EN 1991-1-4. 1.2 Assumptions The assumptions given in FprEN 1990:2022, 1.2 apply to EN 1991-1-9.

1.1 Scope of EN 1991-1-5 (1) EN 1991-1-5 gives principles and rules for calculating thermal actions on buildings, bridges and other structures including their structural members. Principles needed for cladding and other attachments of buildings are also provided. (2) This Part describes the changes in the temperature of structural members. Characteristic values of thermal actions are presented for use in the design of structures which are exposed to daily and seasonal climatic changes. (3) This Part also gives principles for changes in the temperature of structural members due to the paving of hot asphalt on bridge decks. (4) This Part also provides principles and rules for thermal actions acting in structures which are mainly a function of their use (e.g. cooling towers, silos, tanks, warm and cold storage facilities, hot and cold services, etc.). NOTE Supplementary guidance for thermal actions on chimneys is provided in EN 13084-1. 1.2 Assumptions The assumptions given in FprEN 1990:2022, 1.2 apply to EN 1991-1-5.

1.1 Scope of prEN 1993-1-4 This document provides supplementary rules for the structural design of steel structures that extend and modify the application of EN 1993-1-1, EN 1993-1-3, EN 1993-1-5 and EN 1993-1-8 to austenitic, duplex (austenitic-ferritic) and ferritic stainless steels. NOTE 1 Austenitic-ferritic stainless steels are commonly known as duplex stainless steels. The term duplex stainless steel is used in this document. NOTE 2 Information on the durability of stainless steels is given in Annex A. NOTE 3 The execution of stainless steel structures is covered in EN 1090-2 and EN 1090-4. 1.2 Assumptions Unless specifically stated, EN 1990, EN 1991 (all parts), EN 1993-1-1, EN 1993-1-3, EN 1993-1-5 and EN 1993-1-8 apply. The design methods given in prEN 1993-1-4 are applicable if - the execution quality is as specified in EN 1090-2 and EN 1090-4, and - the construction materials and products used are as specified in EN 1993-1-1, EN 1993-1-3, EN 1993 1-5 and EN 1993-1-8, or in the relevant material and product specifications.

(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.
