Scope of EN 1999-1-1

(1) This document gives basic design rules for structures made of wrought aluminium alloys and limited guidance for cast alloys (see Clause 5 and Annex C).

This document does not cover the following unless otherwise explicitly stated in this standard:

- components with material thickness less than 0,6 mm;

- welded components with material thickness less than 1,5 mm;

- connections with:

- steel bolts and pins with diameter less than 5 mm;

- aluminium bolts and pins with diameter less than 8 mm;

- rivets and thread forming screws with diameter less than 3,9 mm.

Assumptions

(1) In addition to the general assumptions of EN 1990 the following assumptions apply:

- execution complies with EN 1090-3;

- the aluminium products comply with EN 573 and the products listed in 2.3.

- the mechanical properties comply with the tabulated values in Parts 2 of the product standards listed in 2.3.

(2) EN 1999 is intended to be used in conjunction with:

- 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
