This document is the 5th Edition of the ECCS European Recommendations for the Buckling of Steel Shells. It is the successor to the 4th Edition, published in 1988, which was very different in style, format and content, though some of the regulatory requirements of the 4th Edition are here retained in the 5th Edition. In the 20 years since the publication of the 4th Edition in 1988, much has changed in the field of metal shell buckling. Extensive research has been undertaken, much new knowledge has been developed, and powerful computational modelling has transformed the field, though much design is still conducted by hand calculation. These changes are reflected in this 5th Edition.
The 5th Edition quotes extensively from the Eurocode EN 1993-1-6 (2007) and is completely compatible with that standard.
However, the Eurocode has no commentary, so the meaning, limitations and origins of many rules are not always clear. This 5th Edition provides an extensive commentary on the existing rules relating to buckling in the Eurocode, but extends far beyond it in giving recommendations, expansions, advice and warnings, explanations and examples, all of which should give the user< considerably more insight and confidence in applying the rules of EN 1993-1-6.
Structure of the document This 5th Edition is divided into two parts. Part I sets out the basic information and general procedures required to undertake all shell buckling calculations according to EN 1993-1-6. It describes the methodology and conceptual principles for numerical analysis, either to derive the basic data that can be used in a straightforward buckling design by hand calculation, or to replace parts of this calculation with numerical assessments, or to carry out a buckling design that is completely based on numerical assessment.
Part II sets out the detailed information for hand calculation procedures when a shell of a particular geometry is being designed for a particular loading condition. Many well-proven engineering formulas, empirical data and simplified rules extracted from numerical parametric studies have been included in this part. In particular, Part II contains radically updated versions of the rules set out in the 4th Edition of the ECCS Recommendations.

Eurocode 3, Part 1.3, Supplementary rules for cold formed members and sheeting (EN 1993-1-3:2004) has been published. This standard replaces pre-standard ENV 1993-1-3:1996 and contains updates and revisions to the pre-standard ENV 1993-1-3.

ECCS has published document No. 114 Preliminary worked examples according to Eurocode 3 Part 1.3 (2000) prepared by ECCS TC 7 using the pre-standard ENV 1993-1-3. The original aim was to check the applicability and accuracy of the pre-standard and assist the practical use of the provisions.

This new publication replaces ECCS document No. 114. The examples have been updated following the provisions given in EN 1993-1-3. Some new examples have been also included. These examples show applicability of design provisions in EN 1993-1-3 in practice. They also help in interpretation of the guidance given in the code.

Chapter 2 contains examples related to one industrial building. Different aspects related to the design of structural components have been included.
-Example A: Roof sheeting
-Example B: Liner trays
-Example C: Purlins
-Example D: Portal frames
-Example E: End wall and wind bracing

Chapter 3 contains additional examples for specific structural elements or features of EN 1993-1-3, which are included to assist in practical use of the provision.
-Example F: C-section in compression and bending about axis of symmetry
-Example G. U-section in bending and compression
-Example H: C-section in compression
-Example I: Hat section upper chord of lattice girder
-Example J: Sheeting with stiffeners in flange and web
-Example K: Inelastic reserve of sheeting
-Example L: Double C-section as end column

The calculations are based on the provisions of EN 1993-1-3. Also parts EN 1993-1-5 and EN 1993-1-1 are required in the calculations. In some cases engineering judgement has been followed. If other methods in addition to Eurocode 3 have been used it has been clearly noted in the examples.

INTRODUCTION

This document replaces the earlier publication by the European Convention of Construc-tional Steelwork, European Recommendations for the Testing of Connections in Profiled Steel Sheeting and Sections, Publication no. 21, first published in 1977 and revised in 1983. Since this publication the use of profiled steel and cold-formed steel has grown considerably, particularly in the use of cold-formed steel sections in structural framing. The current docu-ment has been restructured to conform with guidance in current Eurocodes, which have also been introduced since 1983. The document has been prepared by the Technical Working Group 7.10, part of the ECCS Technical Committee TC7, Cold-formed steel structures.

Aims of the document

This document intends to provide information and guidance on the testing of connections using mechanical fasteners in cold-formed steel structures and steel cladding to determine the design resistance and flexibility. Guidance is provided on the test methods, the interpretation of the results and the preparation of test reports. A list of current references is provided in the appendices.

Scope

Important definitions:
- Fastener: the connecting element in fastening;
- Fastening: the interaction of a fastener with the surrounding material;
- Connection: a group of one or more fastenings.

Types of connections

The recommendations of this document cover conventional mechanical connections using fasteners, such as self tapping and self drilling screws, bolts, rivets and powder-actuated fastenings (powder-actuated fasteners are also referred to as cartridge fired pins).
For further guidance on fastener specification, refer to ECCS publication no. 42 Me-chanical Fasteners (currently under review) for use in steel sheeting and sections.
Fasteners specifically excluded from the recommendations of this document are:
- fasteners for use in composite sandwich cladding panels, these are considered in a separate document (ECCS no. 115: European Recommendations for Sandwich Panels part I – Design, 2001);
- non-standard forms of mechanical fastener such as self-piercing rivets, mechanical clinching and rosettes. These will be the subject of subsequent further guidance docu-ments;
- fasteners in composite structures between steel and other materials;
- high strength friction grip bolts;
- powder actuated fasteners that are covered by European Technical approvals (ETA).

Types of material

The recommendations in this document refer to steel sheet and sections commonly used in profiled metal cladding and cold-formed steel structural sections and hot rolled steel sections used as the substrate for mechanical fasteners. The sheet materials may be unprotected or pro-tected by a suitable coating such as hot dipped galvanising or organic coatings.

Foreword: Bridges link communities and cultures and have always had a key role in an efficient infrastructure network, a prerequisite for a vital economy. Steel in bridges has a long history of more than 100 years following on from the success of cast and wrought iron bridges built in the late 18th century, some of which are still in use today. The creation of an extensive railway network at the beginning of the 20th century would have been impossible without steel.
Although the competition from other building materials has become stronger in the last decades, modern steel bridges still offer a lot of advantages.
Components fabricated in controlled workshop conditions ensure the highest degree of quality. Prefabrication brings
the dual benefits of construction speed and minimum environmental impact during construction. The strength of steel, and the newly developed high-strength steel grades, means that self-weight can be reduced and construction depth
minimized.
Steel structures are also able to fulfill the highest degree of aesthetical quality. Most landmark bridges profit from steel construction.
However, it should not be neglected that steel is also able to offer efficient solutions in terms of initial costs and life cycle costs. This is shown by the success of composite bridges in particular for short and medium spans.
Steel bridges are absolutely innovative. In order to exchange the newest trends in steel bridge construction, international experts have come together for ECCS's 6th International Conference on Steel Bridges in Prague. I really hope that this promotes the exchange of new findings, ideas, and experiences in design, fabrication and erection.
I would like to express my thanks to all speakers providing us with the latest information on steel bridges. Moreover, I would like to thank the organizers, the Czech Constructional Steelwork Association, for the excellent organization of this event.
I hope that the conference contributes to the technological development of steel bridges and wish us informative lectures and many fruitful discussions.

This volume intends at helping in the understanding of the new design rules for member stability in Eurocode 3 Part 1.1 (EN 1993-1-1:2005). In particular, the new recommendations for lateral torsional buckling and beam-column stability in chapter 6.3.3 (4) of Eurocode 3 are concerned. It is divided into two independent parts A and B.
Part A, devoted to the background of the proposed formulae, gives further information on the way the formulae have been built and validated. Moreover, the different basic concepts used in the formulae are detailed, for the two sets of formulae proposed in the code. It is to be noted that a great number of papers prepared within the development of the formulae are made available by means of a CD-Rom that is part of this publication.
Part B is dedicated to practitioners; it contains fully detailed worked examples on isolated members, from basic situations to the most complex one. In addition, an example of design of a member extracted from a frame is also given. Furthermore an annex shows especially the determination of the elastic lateral torsional buckling moment for different loading and support conditions

The influence of climatic parameters such as the drying cycle, salt concentration, UV, SO2, salt time and acidity in the rain on the degradation of coil-coated materials used in the building industry has been systematically studied with respect to edge creep and the nature of the corrosion products formed in the edge areas. From the results, the influence of each parameter alone or in combination has been determined with respect to the degradation of pre-painted hot-dip galvanised and pre-painted Aluzinc materials. From the results, the influence of the climatic factors with regard to edge creep has also been determined.

For pre-painted hot-dip galvanised steel, the importance of primary factor decreased in the following order: SO2 > chloride concentration> acidity = salt time > wetness = drying cycle> UV.

For pre-painted Aluzinc, the primary factors decreased in the following order: chloride concentration> SO2 = wetness = drying cycle> salt time > acidity > UV.

The results have also been compared to those obtained after two years of exposure at Bohus Malmôn (marine environment) and Cayenne city (tropical environment). The results indicate that only tests including SO2 were able to mimic the nature of corrosion products found after two years of exposure at Bohus Malmôn. From the results a new cyclic corrosion test is proposed.
This test gives a good acceleration factor without losing correlation to field data. The test also shows good correlation to the field data with respect to the nature of the corrosion products formed at the edge area.
