Since publication of the second edition of Design of Structural Elements there have been two major developments in the field of structural engineering which have suggested this new edition. The first and foremost of these is that the Eurocodes for concrete, steel, masonry and timber design have now been converted to full EuroNorm (EN) status and, with the possible exception of the
steel code, all the associated UK National Annexes have also been finalised and published. Therefore, these codes can now be used for structural design, although guidance on the timing and circumstances under which they must be used is still awaited. Thus, the content of Chapters 8 to 11 on, respectively, the design of concrete, steel, masonry and timber structures has been completely revised to comply with the EN versions of the Eurocodes for these materials. The opportunity has been used to expand Chapter 10 and include several worked examples on the design of masonry walls subject to either vertical or lateral loading or a combination of both.
The second major development is that a number of small but significant amendments have been made to the 1997 edition of BS 8110: Part 1 on concrete design, and new editions of BS 5628: Parts 1 and 3 on masonry design have recently been published. These and other national standards, e.g. BS 5950 for steel design and BS 5268 for timber design, are still widely used in the UK and beyond. This situation is likely to persist for some years, and therefore the decision was taken to retain the chapters on British Standards and where necessary update the material to reflect latest design recommendations. This principally affects the material in Chapters 3 and 5 on concrete and masonry design.

The chapters on Eurocodes are not self-contained but include reference to relevant chapters on British Standards. This should not present any problems to readers familiar with British Standards, but will mean that readers new to this subject will have to refer to two chapters from time to time to get the most from this book. This is not ideal, but should result in the reader becoming familiar with both British and European practices, which is probably necessary during the transition phase from British Standards to Eurocodes. The main motivation for preparing this new edition was to update the text in Chapters 4 and 6 on steel and timber design to conform with the latest editions of respectively BS 5950: Part 1 and BS 5268: Part 2. The opportunity has also been taken to add new material to Chapters 3 and 4. Thus, Chapter 3 on concrete design now includes a new section and several new worked examples on the analysis and design of continuous beams and slabs. Examples illustrating the analysis and design of two-way spanning slabs and columns subject to axial load and bending have also been added.

The section on concrete slabs has been updated. A discussion on flooring systems for steel framed structures is featured in Chapter 4 together with a section and several worked examples on composite floor design. Work on converting Parts 1.1 of the Eurocodes for concrete, steel, timber and masonry structures to full EN status is still ongoing. Until such time that these documents are approved the design rules in pre-standard form, designated by ENV, remain valid. The material in Chapters 8, 9 and 11 to the ENV versions of EC2, EC3 and EC5 are still current. The first part of Eurocode 6 on masonry design was published in pre-standard form in 1996, some three years after publication of the first edition of this book. The material in Chapter 10 has therefore been revised, so it now conforms to the guidance given in the ENV. I would like to thank the following who have
assisted with the preparation of this new edition: Professor Colin Baley for preparing Appendix C; Fred Lambert, Tony Threlfall, Charles Goodchild and Peter Watt for reviewing parts of the manuscript.
