Assessment of Stresses in Post-Tensioned Concrete Bridges
Abstract This paper presents the results of trials carried out on a post-tensioned concrete six-cell box structure to determine the in-situ stress levels. The techniques used were based on the stress-relief which occurs during the removal of concrete cores and the re-establishment of the stress fields using a novel jacking technique. The estimated stresses were compared with those predicted using a finite element analysis and a good correlation was obtained. The measured stresses generally ranged between 6 and 9 N/mm2 although local variations were observed. The elastic constants for the concrete were assessed using the results of the jacking tests and laboratory compression tests.
