ÖNORM EN 1999-1-1

This document gives basic design rules for structures made of wrought aluminium alloys and limited guidance for cast alloys. 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
