ENDURING STRENGTH

The long-term effectiveness of posttensioning in bridges depends on the resiliency of the tendons, and various factors related to construction and marine environments also come into play. This article discusses some ways by which these sinews can be better protected, thereby enhancing the rehabilitative efforts of bridge engineers to deal with corrosion in posttensioned concrete bridges. The bridge inspection program of the state of Florida, aimed at ensuring the safety and soundness of its posttensioned bridge inventory, is used as a case example. An FHWA survey of 50 U.S. state Departments of Transportation, conducted to determine which posttensioned concrete bridges may be susceptible to the corrosion problems first detected in Florida, is also discussed.
