ULTIMATE LOAD BEHAVIOR OF POST-TENSIONED PRESTRESSED CONCRETE GIRDER BRIDGE THROUGH IN-PLACE FAILURE TEST
This study aimed to explore the failure behavior of actual prestressed concrete I-girder bridges at an ultimate load stage and to examine the true load-carrying capacity at an actual slab-girder bridge system. A 30-year-old prestressed concrete girder bridge was load-tested up to the ultimate load stage at the actual site. A special loading system that is appropriate for the full-scale load test of a bridge was designed. The service load and ultimate load behaviors were observed by automatic measurement of all important values including concrete and steel strains, deflections, and crack widths. The present test results will provide useful and important field data that can be used for the realistic safety assessment as well as improvements in the design of the prestressed concrete girder bridges.
