Book Description
The concept of post-tensioning has been recognized for over a century. Interestingly, early developments started with external tendons, but failed to be recognized as a major construction technique for two main reasons: - Low tensile performance of early steels in combination with a poor knowledge of concrete creep and shrinkage properties, - Lack of a durable corrosion protection. With the technological progress, external tendons became increasingly popular in the 1980’s, as a post-tensioning method enabling inspection and, if necessary, replacement of tendons without demolition of structural members. Towards the end of the last century, more than 50 bridges have been built with external tendons, first in France and soon gaining traction in other countries. FIP published a state-of the-art report in May 1996 to provide a review of the application of external tendons, describing specific material problems and methods for dealing with them. 25 years have passed and, while the engineering principles covered by the FIP report remain unchanged, the context has evolved: - External tendons and construction methods have kept evolving with better materials, ever longer spans, and tighter schedules. - Normalization frame in Europe changed, Severe durability issues have occurred in some countries from which the industry can extract good knowledge of the causes and how to avoid similar problems in the future. This new fib bulletin has been prepared with the aim to reflect the current state of the art and encompass the knowledge amassed in the last quarter of century with chapters covering from the design and approval of systems and materials to installation, quality control and monitoring. The last chapter is a compilation of structures worldwide covering all sorts of materials, typologies and construction methods, which might be a source of inspiration for owners and designers alike.

Book Description
Addressed to designers and even more so to owners and project managers, this part is meant as a guide to an efficient selection of designers and contractors, and to the preparation of fair contracts providing high quality at reasonable cost. Clearly, a good design must be paid for at its real cost; economising on the design cost can be extremely counterproductive for the owner when considering the final whole-life cost of the project. In addition, it was considered very important to address the designer’s responsibilities and relations with other participants in large projects, and finally design philosophy itself. Part 2 – Design and construction aspects This more technical part is mainly addressed to bridge designers and devoted to a systematic analysis of structural and constructional bridge concepts. Considering the importance of erection techniques in the development of bridge design, this second part of the guide starts by a description of the different construction methods, their advantages and draw-backs, their particularities and, of course, by defining the domain of their most efficient applications. Another main chapter is devoted to the proper design of cross-sections. And finally, a third main chapter deals in detail with the influence of construction techniques on design.

Book Description
This manual contains updated information on the current practices in the use, design, and construction of post- tensioning. The 6th Edition has been extensively rewritten and expanded from the 5th Edition. The Manual contains 12 new chapters that give design guidance on modern applications of post-tensioning. All of the original chapters have been totally revised and modified to reflect the current industry practices. New topics include Seismic Design, Post-Tensioned Concrete Floors, Parking Structures, Slab-on-Ground, Bridges, Stay Cables, Storage Structures, Barrier Cables, Dynamic and Fatigue, Durability, Inspection and Maintenance, and Field and Plant Certification. The Manual provides the industry standard for design and construction of post-tensioned structures. This book is an invaluable resource for practicing engineers, architects, students, educators, contractors, inspectors, and building officials. The 6th Edition of the Post-Tensioning Manual provides basic information and the essential principles of post-tensioning.
