Full Description

This book provides an overview of post-tensioning (PT) in reinforced concrete bridge structures. It specifically addresses corrosion issues that were initially unforeseen but subsequently occurred, raised concerns regarding structural integrity and long-term viability.

It begins by exploring the introduction and background of PT bridge development, addressing post-tensioning systems and the various types of PT bridge construction methods. It also covers corrosion issues and failures that have previously occurred, and other designs for durability. Further, it goes into the details of experimental investigations of corrosion-caused bridge PT tendon failures, and the modeling efforts of wire and strand fractures. Lastly, it provides an assessment of the path forward, suggesting alternatives for current inspection and condition assessment.

This book is highly recommended for graduate and postgraduate students of civil, structural, and mechanical engineering. It will also be an interesting read for structural and civil engineers, and researchers involved with integrity assurance of PT structures.
