Available in PDF, EPUB and Kindle. Book excerpt: Post-tensioned concrete has proved to be an economically competitive and safe form of bridge construction enabling concrete to be used for bridges of significantly longer spans than was previously possible using untensioned reinforced concrete. While France has been foremost in pioneering the use of prestressed concrete for bridge construction, the UK has also made significant contributions through its research and innovation. This book reports the findings of a joint study group set up by the French and UK central government highway agencies to liaise on issues concerning post-tensioned concrete bridges and seek solutions for problems where they exist. Throughout the years, these bodies have accumulated a wealth of knowledge, most of which has been unpublished until now. This book makes available for the first time the valuable experiences of the authors, most of whom have been personally responsible for formulating and administering the relevant rules and regulations in their respective countries. Written in both English and French, this state-of-the-art report will be of use to the designers, constructors and managers of post-tensioned concrete bridges and the manufacturers of post-tensioning systems. It contains extensive historical and technical information with numerous references and bibliographies at the end of most chapters. The book considers the potential difficulties associated with construction and maintenance, and how these can be identified and combated. It concludes with a look at the future of post-tensioned concrete bridges, focusing on the further development of regulatory requirements.
