‘Stress ribbon bridges’ is the term used to describe structures formed by a very slender concrete deck in the shape of a catenary. They can be designed with one or more spans and are characterized by successive and complementary smooth curves. These curves blend into the natural environment and their forms; the most simple and basic of structural solutions, clearly articulate the flow of internal forces which can be erected without undue pressure on the environment.
This new and fully updated edition of Stress Ribbon and Cable-supported Pedestrian Bridges examines all aspects of the design of these structures. Starting with a brief history, the title describes structural types, addresses general design criteria, current technology, static and dynamic analysis and discusses the results of the static and dynamic loading tests. Illustrated throughout, Stress Ribbon and Cable-supported Pedestrian Bridges provides the latest examples of outstanding structures and fully revised to bring the text in to line with the Eurocodes.
Stress Ribbon and Cable-supported Pedestrian Bridges: provides a definitive practical guide to stress ribbon and cable-supported bridges focuses on the very latest examples of these structures with international case studies includes over 500 illustrations to complement the text incorporates the latest Eurocodes
features the most up to date technology.
Stress Ribbon and Cable-supported Pedestrian Bridges is essential reading to practising engineers who wish to understand the premises upon which the rules are based and researchers who wish to develop the subject further and students who wish to delve into the background behind the current loading rules.
