Shear Behavior of Spliced Post-Tensioned Girders with Ungrouted Tendons

The objective of this Implementation Project is to test the implementation of the previously developed research products for cases in which ducts are not grouted or are filled with flexible fillers such as wax. By conducting targeted tests on TxDOT spliced girders with ungrouted tendons, the implementation of the previously developed design expressions to such cases will be accomplished. The calibration of shear capacity reduction factors that consider the influence of duct size and duct material will be necessary. The case of ungrouted tendons is pertinent to intermediate construction stages before bridges are completed or in cases where TxDOT may consider using fillers that have not been tested or used previously.
