DURABILITY OF POST-TENSIONED CONCRETE BRIDGES

This paper addresses the durability problems in posttensioned concrete bridges that have been discovered in recent years. These includes corrosion failure of tendons and anchorages; loss of tendons, especially in a segmental bridge, may cause collapse of the structure. Detailed case studies of 2 bridges are given. The roles of anchorage details, grouting procedures, environmental conditions, and workmanship issues in corrosion failure are outlined. The need for and methods of inspection are discussed. Current changes in construction practice are summarized.
