scope:

(1) EN 1999-1-1 gives basic design rules for structures made of wrought aluminium alloys and limited guidance for cast alloys (see section 3). NOTE - Minimum material thickness may be defined in the National Annex. The following limits are recommended - if not otherwise explicitly stated in this standard: - components with material thickness not less than 0,6 mm; - welded components with material thickness not less than 1,5 mm; - connections with: o steel bolts and pins with diameter not less than 5 mm; o aluminium bolts and pins with diameter not less than 8 mm; o rivets and thread forming screws with diameter not less than 4,2 mm (2) The following subjects are dealt with in EN 1999-1-1: Section 1: General Section 2: Basis of design Section 3: Materials Section 4: Durability Section 5: Structural analysis Section 6: Ultimate limit states for members Section 7: Serviceability limit states Section 8: Design of joints Annex A Execution classes Annex B Equivalent T-stub in tension Annex C Materials selection Annex D Corrosion and surface protection Annex E Analytical models for stress strain relationship Annex F Behaviour of cross section beyond elastic limit Annex G Rotation capacity Annex H Plastic hinge method for continuous beams Annex I Lateral torsional buckling of beams and torsional or flexural-torsional buckling of compression members Annex J Properties of cross sections Annex K Shear lag effects in member design Annex L Classification of connections Annex M Adhesive bonded connections (3) Sections 1 to 2 provide additional clauses to those given in EN 1990 "Basis of structural design". (4) Section 3 deals with material properties of products made of structural aluminium alloys. (5) Section 4 gives general rules for durability. (6) Section 5 refers to the structural analysis of structures, in which the members can be modelled with sufficient accuracy as line elements for global analysis. (7) Section 6 g
