Niels Jørgen Gimsing & Christos Georgakis, Technical University of Denmark, LyngbyProfessor Gimsing is Professor Emeritus in the Department of Civil Engineering at the Technical University of Denmark and a Consulting Bridge Engineer. He consulted on the design for numerous landmark bridges including the Femern Bridge, third bridge across the Firth of Forth in Scotland, the Messina Strait Bridge and the 47km long motorway bridge across the Gulf of Thailand, and was a Finalist in the Millennium Bridge Competition for a pedestrian bridge across the Thames at St. Paul's Cathedral. He has won numerous design, teaching and research awards for his work within the structural engineering community and is the author of Cable Supported Bridges 2e (Wiley, 1997) and co-author of The Messina Strait Bridge (CRC, 2009).Dr. Christos Georgakis is Associate Professor in Structural Engineering and Prof Gimsing’s teaching successor at DTU. He has particular experience in relation to dynamic actions from his work at the Wind Tunnel Laboratory in Copenhagen and is also involved in several research projects dealing with the dynamics of slender bridges such as the Millennium Bridge in London.

"Pleasingly, this book is comprehensively referenced for those wishing to delve into further detail. While not a manual for detailed design, the contents of the book provide a comprehensive knowledge base for students and experienced engineers seeking to expand their understanding of these structures, which themselves continually challenge the boundaries of what is possible." (Engineering and Computational Mechanics, 11 October 2013)"The book is well organised into components: cables, pylons and anchorages, and goes into every possible detail ... The book strikes a perfect balance between theory and practice. Professors Gimsing and Georgakis set out to give us an authoritative book about the evolution, trends and technical response of cable-supported bridges, and they have achieved that well." (The Structural Engineer, 1 April 2012)"Comprehensively updated to discuss improvements in technology in the fourteen years since its last printing, the third edition of this volume on the theory and design of cable supported bridges provides a detailed, element-by-element discussion of the core principles of suspension bridge design."
