(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

(1) EN 1999-1-3 gives the basis for the design of aluminium alloy structures with respect to the limit state of fracture induced by fatigue.
(2) EN 1999-1-3 gives rules for:
-   Safe life design;
-   damage tolerant design;
-   design assisted by testing.
(3) EN 1999-1-3 is intended to be used in conjunction with EN 1090-3 "Technical requirements for the execution of aluminium structures" which contains the requirements necessary for the design assumptions to be met during execution of components and structures.
(4) EN 1999-1-3 does not cover pressurised containment vessels or pipe-work.

(1)P   EN 1999-1-4 gives design requirements for cold-formed trapezoidal aluminium sheeting. It applies to cold-formed aluminium products made from hot rolled or cold rolled sheet or strip that have been cold-formed by such processes as cold-rolled forming or press-breaking. The execution of aluminium structures made of cold-formed sheeting is covered in EN 1090-3.
NOTE   The rules in this part complement the rules in other parts of EN 1999-1.
(2)   Methods are also given for stressed-skin design using aluminium sheeting as a structural diaphragm.
(3)   This part does not apply to cold-formed alumi¬nium profiles like C-, Z- etc profiles nor cold-formed and welded circular or rectangular hollow sections.
(4)   EN 1999-1-4 gives methods for design by calculation and for design assisted by testing. The methods for the design by calculation apply only within stated ranges of material properties and geometrical properties for which sufficient experience and test evidence is available. These limitations do not apply to design by testing.
(5)   EN 1999-1-4 does not cover load arrangement for loads during execution and main-tenance.

Supplementary to Part 1-1. Additional and varied rules to be used for the design of aluminium alloys structures which are required to avoid premature structural collapse and to limit the spread of fire in the accidental situation of exposure to fire.

This Part 2 gives the basis for the design of aluminium alloy structures with respect to the limit state of fatigue induced fracture. Design for other limit states is covered in Part 1. This Part 2 gives rules for design by the following methods: - safe life; - damage tolerance; - design by testing. This Part 2 contains the manufacturing quality requirements necessary to ensure that the design assumptions are met in practice.

This European prestandard deals with the design of aluminium alloy structures for the accidental situation of fire exposure and is intended to be used in conjunction with prENV 1999-1-1:1997 and ENV 1991-2-2:1995. This European prestandard only identifies differences from, or supplements to, normal temperature design. This document deals only with passive methods of fire protection. Active methods are not covered. This European prestandard applies to structures which, for reasons of general fire safety, are required to avoid premature collapse of the structure in exposure to fire (load-bearing function).

This European Prestandard gives a general basis for the design of buildings and civil and structural engineering works in aluminium alloy. The following subjects are dealt with in this initial version of this European Prestandard: -Section 1: General; -Section 2: Basis of design; -Section 3: Materials; -Section 4: Serviceability limit states; -Section 5: Ultimate limit states (members); -Service 6: Connections subject to static loading; -Section 7: Fabrication and execution; -Section 8: Design assisted by testing.
