EN 1999 applies to the design of buildings and civil engineering and structural works in aluminium. It complies with the principles and requirements for the safety and serviceability of structures, the basis of their design and verification that are given in EN 1990 - Basis of structural design. (2) EN 1999 is only concerned with requirements for resistance, serviceability, durability and fire resistance of aluminium structures. Other requirements, e. g. concerning thermal or sound insulation, are not considered. (3) EN 1999 is intended to be used in conjunction with: EN 1990 Basis of structural design EN 1991 Actions on structures European Standards for construction products relevant for aluminium structures EN 1090-1: Execution of steel structures and aluminium structures - Part 1: Conformity assessment of structural components5) EN 1090-3: Execution of steel structures and aluminium structures - Part 3: Technical requirements for aluminium structures6) (4) EN 1999 is subdivided in five parts: EN 1999-1-1 Design of Aluminium Structures: General structural rules EN 1999-1-2 Design of Aluminium Structures: Structural fire design EN 1999-1-3 Design of Aluminium Structures: Structures susceptible to fatigue EN 1999-1-4 Design of Aluminium Structures: Cold-formed structural sheeting EN 1999-1-5 Design of Aluminium Structures: Shell structures EN 1999-1-3 (1) EN 1999-1-3 gives the basis for the design of aluminium alloy structures with respect to the limit state of fracture induced by fatigue. (2) EN 1999-1-3 gives rules for: Safe life design; damage tolerant design; design assisted by testing. 5) To be published 6) To be published (3) EN 1999-1-3 is intended to be used in conjunction with EN 1090-3 "Technical requirements for the execution of aluminium structures" which contains the requirements necessary for the design assumptions to be met during execution of components and structures. (4) EN 1999-1-3 does not cover pressurised containment vessels or pipe-work. (5) The following subjects are dealt with in EN 1999-1-3: Section 1: General Section 2: Basis of design Section 3: Materials, constituent products and connecting devices Section 4: Durability Section 5: Structural analysis Section 6: Ultimate limit state of fatigue Annex A: Basis for calculation of fatigue resistance [normative] Annex B: Guidance on assessment by fracture mechanics [informative] Annex C: Testing for fatigue design [informative] Annex D: Stress analysis [informative] Annex E: Adhesively bonded joints [informative] Annex F: Low cycle fatigue range [informative] Annex G: Influence of R-ratio [informative] Annex H: Fatigue strength improvement of welds [informative] Annex I: Castings [informative] Annex J: Detail category tables [informative] Annex K: Hot spot reference detail method [informative] Bibliography
