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.
