Durability of Prestressed Concrete Highway Structures

摘要

The synthesis will be of interest to bridge designers, materials engineers, maintenance engineers, and others concerned with the durability of prestressed concrete bridges. Information is presented on the factors affecting the durability of prestressed concrete. Prestressed concrete bridges require special attention because the capacity of the structure is strongly dependent on the prestressing force. The report of the Transportation Research Board reviews the factors affecting the durability of prestressed bridge components and describes methods of detecting and assessing deterioration, preventive maintenance, repair, and methods of improving durability in new structures.
