5 For Fiona and Sean

6 ACKNOWLEDGEMENTS I would like to express my deep gratitude to all those who helped me with this project. I am indebted to my colleagues in the Department of Civil and Structural Engineering at UMIST and in the Department of Civil Engineering at Stanford University. Smail Derouiche and Kirti Ruikar helped enormously with testing the exercises. Thanks also to my students from whom I have learned so much and to the Autodesk team in Guildford, UK and San Rafael, California. My special thanks to Grace, Fiona and Sean for everything.
