PREFACE:

The main purpose of the third edition remains again to present principles, relevant considerations and sample designs for some of the major types of steel-framed buildings. All buildings can be framed in different ways with different types of joints and analysed using different methods. 

Member design for ultimate conditions is specified. Projects are selected to show alternative designs for the same structure. Designs are now to confirm to limit state theory according to the British steel codes of practice and the new Eurocodes of practice. Design principles are set out briefly and designs made to the British codes of practice and to the Eurocodes of practice in most cases for comparison.

 Many more design calculations and checks are required for the limit state codes of practice than for the previous elastic codes of practice, and thus not all load cases or details checks can be carried out for every design project. However, further necessary design work is indicated in these cases.

 Though computer methods, mainly for analysis, but also increasingly used for the member and connection design, are now the design office procedural norm, approximate, manual methods are still of great importance.

 These are required mainly to obtain sections for computer analysis and to check final design. The book, as in the case of the second edition, is aimed at final year students, candidates of master’s degree courses in structural engineering and young engineers in industry. Fundamental knowledge of the methods of structural analysis and design from a basic design course is assumed. 

The preparation of this edition of this book has not been confined to a single person, as the title page may suggest. In this work, I have been helped by many, both directly and indirectly, and my thanks are due and gratefully given to them all and in particular to John Ellis, Academic Programme Manager, Liverpool John Moores University; Paul Hodgkinson, Liverpool John Moores University for providing the figures and drawings; and Professor Aldo Cauvin Giuseppe Stagnitto, Department of Structural Mechanics, University of Pavia, Italy for providing comprehensive material used as the main bases for Chapter 1..

None of this, however, would have been possible without the generous cooperation of my wife Shadha and sons Haydar and Yassier. I am, therefore, extremely grateful for their continuous support and help. 

I hope that many students and engineers will find this current edition as helpful in their studies as the first and second editions were to my students and myself. Then all the efforts put into this work would have been well worthwhile.

The main purpose of the second edition is again to present principles, relevant considerations and sample designs for some of the major types of steel-framed buildings. All buildings can be framed in different ways with different types of joints and analysed using different methods. Member design for ultimate conditions is specified. Projects are selected to show alternative designs for the same structure. 

Designs are now to conform to limit state theory – the British steel codes of practice and the new Eurocodes of practice. Design principles are set out briefly and designs made to the British codes of practice only.

 Reference is made to the Eurocodes of practice in one special case. Many more design calculations and checks are required for the limit state codes of practice than for the previous elastic codes of practice, and thus not all load cases or detailed checks can be carried out for every design project. However, further necessary design work is indicated in these cases. 

Though computer methods, mainly for analysis, but also increasingly used for member and connection design, are now the design office procedural norm, approximate, manual methods are still of great importance. These are required mainly to obtain sections for computer analysis and to check final designs.

 The book, as in the case of the first edition, is aimed at final year students, candidates on master’s degree courses in structural engineering and young engineers in industry. Fundamental knowledge of the methods of structural analysis and design from a basic design course is assumed.
