Eurocode 9 Design of aluminium structures 12

Eurocode 9 Design of aluminium structures 12 This series of Designers'' Guides to the Eurocodes provides comprehensive guidance in the form of design aids, indications for the most convenient design procedures and worked examples. The books also include background information to aid the designer in understanding the reasoning behind and the objectives of the codes. All of the individual guides work in conjunction with the Designers'' Guide to Eurocode: Basis of Structural Design. EN 1990. Aluminium is not as widely used for structural applications as it could be, partly as a result of misconceptions about material strength and durability but largely because engineers and designers have not been taught how to use it - additional specific design checks are needed. A material with unique properties that need to be exploited and worked with, aluminium has many benefits and, when used correctly, the results are light, durable, cost effective structures. EN 1999, Eurocode 9: Design of aluminium structures, details the requirements for resistance, serviceability, durability and fire resistance in the design of buildings and other civil engineering and structural works in aluminium. This guide provides the user with guidance on the interpretation and use of Part 1-1: General structural rules and Part 1-4: Cold-formed structural sheeting of EN 1999, covering material selection and all main structural elements and joints.

National foreword

This Draft for Development has been prepared by Subcommittee B/525/9 and is theEnglish language version of ENV 1999-1-2:1998 Eurocode 9: Design of aluminiumstructures Part 1-2: General rules - structural fire design, as published by theEuropean Committee for Standardization

ENV 1999-1-2:1998 results from a programme of work sponsored by the EuropeanCommission to make available a common set of rules for the structural andgeotechnical design of building and civil engineering works

This publication is not to be regarded as a British Standard.

An ENV is made available for provisional application, but does not have the status

of a European Standard The aim is to use the experience gained to modify the ENV

so that it can be adopted as a European Standard

Fire safety in the UK is covered by national regulations in the form of BuildingRegulations, and in particular Approved Document B (1992 edition) of thoseregulations There are no current British Standards that give a method of calculatingfire resistance of structural members of Aluminium or its alloys

The values for certain parameters in the ENV Eurocodes may be set by individualCEN members so as to meet the requirements of national regulations Theseparameters are designated by × in the ENV

The BSI technical committee responsible do not propose any changes to the boxedvalues for this code

The ENV allows (clause 2.4.1) structural analysis by several methods For verifyingstandard fire resistance requirements, a member analysis is usually consideredsufficient

Users of this documents are invited to comment on its technical content, ease of useand any ambiguities and anomalies These comments will be taken into accountwhen preparing the UK national response to CEN on the question of whether theENV can be converted to an EN

Comments should be sent in writing to the secretary of Subcommittee B/525/9, BSI,

389 Chiswick High Road, London W4 4Al, quoting the document reference, therelevant clause and, where possible, a proposed revision, within 2 years of the issue
