This British Standard is the UK implementation of EN 1999-1-3:2007. It supersedes DD ENV 1999-2:2000 which is withdrawn. Details of superseded British Standards are given in the table below.
EN 1999 is intended to be used with Eurocodes EN 1990 – Basis of Structural Design, EN 1991 – Actions on structures and EN 1992 to EN 1999, where aluminium structures or aluminium components are referred to.
EN 1999-1-3 is one of five parts EN 1999-1-1 to EN 1999-1-5 each addressing specific aluminium components, limit states or type of structure. EN 1999-1-3 describes the principles, requirements and rules for the structural design of aluminium components and structures subjected to fatigue actions.
Numerical values for partial factors and other reliability parameters are recommended as basic values that provide an acceptable level of reliability. They have been selected assuming that an appropriate level of workmanship and quality management applies.
Scope of EN 1999:
(1) P 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
Scope of 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.
(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
