Standards Development

Scope

(1) This document deals with the design of aluminium structures for the accidental situation of fire exposure and is intended to be used in conjunction with EN 1999-1-1, EN 1999-1-3, EN 1999-1-4 and EN 1999-1-5. This document only identifies differences from, or supplements to, normal temperature design.

(2) This document applies to aluminium structures required to fulfil a load bearing function.

(3) This document gives principles and application rules for the design of structures for specified requirements in respect of the aforementioned function and the levels of performance.

(4) This document applies to structures, or parts of structures, that are within the scope of EN 1999-1-1 and are designed accordingly.

(5) The methods given in this document are applicable to the following aluminium alloys: EN AW-3004 – H34 EN AW-5083 – O and H12 EN AW-6063 – T5 and T6 EN AW-5005 – O and H34 EN AW-5454 – O and H34 EN AW-6082 – T4 and T6 EN AW-5052 – H34 EN AW-6061 – T6

(6) The methods given in this document are applicable also to other aluminium alloy/tempers of EN 1999-1-1, provided that either all necessary information on properties at elevated temperatures are available or the simplified assumptions in 5.2.1 are applied.

Purpose

The amendment of EN 1999-1-2 will primarily consider the following:

—Update of references;

—Alignment to N3662 Update on harmonization of common clauses of Eurocode fire parts.
