Varina Enon Tendon Failure

The two parallel 28 span Varina Enon bridges were completed in 1990. These precast post-tensioned structures were constructed with the latest concrete and post-tensioning technologies and were expected to provide relative maintenance free performance for more than 100 years. In addition to cables that hang from two towers the structures are supported by more than 500 tendons with grouted post-tensioned strands. On May 22, 2007 tendon SP12T15 was found failed during a biannual inspection. The failed tendon raised concerns about the condition of other tendons in the structures and the Federal Highway Administration (FHWA) authorized emergency funding to replace the failed tendon, determine the condition of other tendons, make needed repairs and determine the cause of the failure. This paper presents the results from the evaluation of the Varina Enon tendon failure.
