478 pages - Publisher: Blackwell Science; 2nd edition (May, 1988). Language: English - ISBN-10: - ISBN-13: 9416. Cable-stayed Bridges describes the evolution, theory and design of cable-stayed bridges, examining the various types, structural details, methods. Since the first edition of this book was published a decade ago, there have been considerable developments in the state of the art of cable stayed bridges. This second edition includes a range of new bridge examples, including some from Europe, the USA and Canada, and information on cable stayed floating bridges. Two computerised design methods have been added to the chapter on analysis, and further details have been included on wind tests.
