Prestressed Beam End Repair Testing: BR27568 Experimental Shear Capacity Comparison Between Repaired and Unrepaired Girder Ends

Status:  Active
Project Start Date:  03/22/2017

Summary:

The research would determine if the repair was sufficient to restore the original strength of the girder end in shear. Load testing to failure will be conducted on two repaired girder ends and two unrepaired girder ends that will be removed from the bridge. Objectives include a comparison of the failure load between the repaired ends and the unrepaired ends. The test results also will provide some answers to questions on whether shotcrete is a structural repair or if it is just a covering over of deterioration.
