EN 1999 applies to the design of buildings and civil engineering and structural works made of 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.
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.
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: Requirements for conformity assessment of structural components
— EN 1090-3: Execution of steel structures and aluminium structures – Part 3: Technical requirements for aluminium structures.
EN 1999-1-1 gives basic design rules for structures made of wrought aluminium alloys and limited guidance for cast alloys.
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:
— steel bolts and pins with diameter not less than 5 mm;
— aluminium bolts and pins with diameter not less than 8 mm;
— rivets and thread forming screws with diameter not less than 3,9 mm
