Preface to Design of Steel Structures
The General rules and rules for buildings of part 1-1 of Eurocode 3 constitute the core of the code procedures for the design of steel structures.
They contain the basic guidance for structural modeling and analysis of steel frameworks and the rules for the evaluation of the resistance of structural members and components subject to different loading conditions.
According to the objectives of the ECCS Eurocode Design Manuals, it is the objective of this book to provide a mix of “light” theoretical background, explanation of the code prescriptions and detailed design examples.
Consequently, this book is more than a manual: it provides an all-in-one source for an explanation of the theoretical concepts behind the code and detailed design examples that try to reproduce real design situations instead of the usually simplified examples that are found in most textbooks.
This book evolved from the experience of teaching Steel Structures according to ENV 1993-1-1 since 1993. It further benefited from the participation in Technical Committees TC8 and TC10 of ECCS where the background and the applicability of the various clauses of EN 1993-1-1 were continuously questioned.
This book covers exclusively part 1-1 of Eurocode 3 because of the required level of detail. Forthcoming volumes discuss and apply most of the additional parts of Eurocode 3 using a consistent format.
Chapter 1 introduces general aspects such as the basis of design, material properties, and geometric characteristics and tolerances, corresponding to chapters 1 to 4 and chapter 7 of EN 1993-1-1.
It highlights the important topics that are required in the design of steel structures. Structural analysis is discussed in chapter 2, including structural modeling, global analysis, and classification of cross-sections, covering chapter 5 of EN 1993-1
The design of steel members subjected to various types of internal force (tension, bending and shear, compression and torsion) and their combinations is described in chapter 3, corresponding to chapter 6 of EN 1993-1-1.
Chapter 4 presents the design of steel structures using 3D elastic analysis based on the case study of a real building. Finally, chapter 5 discusses plastic design, using a pitched-roof industrial building to exemplify all relevant aspects.
Furthermore, the design examples provided in this book are chosen from real design cases. Two complete design examples are presented: i) a braced steel-framed building, and ii) a pitched-roof industrial building.
The chosen design approach tries to reproduce, as much as possible, real design practice instead of more academic approaches that often only deal with parts of the design process.
This means that the design examples start by quantifying the actions. They then progress in a detailed step-by-step manner to global analysis and individual member verifications.
The design tools currently available and adopted in most design offices are based on software for 3D analysis.
Consequently, the design example for multi-story buildings is analyzed as a 3D structure, all subsequent checks being consistent with this approach.
This is by no means a straightforward implementation since most global stability verifications were developed and validated for 2D structures.
The authors are indebted to Prof. Reidar Bjorhovde who carried out a detailed technical review of the manuscript and provided many valuable comments and suggestions.
Warm thanks to Prof. David Anderson who carried out an additional detailed revision of the book and also made sure that the English language was properly used.
Further thanks to Liliana Marques and José Alexandre Henriques, Ph.D. students at the University of Coimbra, for the help with the design examples of chapter 4.
Additional thanks to Prof. Tiago Abecasis who spotted numerous “bugs” in the text. Finally, thanks to Filipe Dias and the staff of cmm and ECCS for all the editorial and typesetting work, making it possible to bring to an end two years of work in this project.
