Abstract:

The spliced girder research program conducted as part of TxDOT Project 0-6652 investigated the implications of spliced girder technology and resulted in updating the AASHTO LRFD Bridge Design Specification’s (AASHTO LRFD) General Procedure for shear design, which was originally developed based on the results of small-scale panel tests. However, TxDOT Project 0-6652 evaluated large-scale post-tensioned members with grouted ducts only. Thus, the AASHTO LRFD general shear design provisions are currently based on an incomplete database of specimens and could result in potentially poorly designed spliced girders with the ungrouted ducts. Thus, large-scale testing was necessary to investigate the response of ungrouted post-tensioning systems.
