Experimental Shear Capacity Comparison Between Repaired and Unrepaired Girder EndsStatus: CompleteReport Date: 03/12/2018 Summary: Researchers evaluated an innovative technique for repairing the damaged ends of prestressed, reinforced concrete bridge girders with a reinforcement cage and hydraulic cement. The repair method appeared to work well in the field, but the technique had not been scientifically analyzed. Lab testing of repaired and unrepaired prestressed, reinforced girders from the same bridge and manufacturing batch showed that the repair method restored damaged girders to their previous shear strength Final Deliverables: Report #2018-07 Research Summary Related Materials: Video: 2019 SGIA Video Award Winner: Bridge Beam End Reconstruction - (Video/Webinar) Girder testing video - (Video/Webinar) Affordable Bridge Girder End Repair Method Restores Concrete Beams - (Blog Post) KSTP News: MnDOT Uses Innovative Bridge Repair Method to Save Time, Money - (Video/Webinar) Alternative Bridge Design Method Saves Time, Money (MnDOT Newsline) - (News/Publication Article) Alternative Bridge Design Method Saves Time, Money (Accelerator newsletter) - (News/Publication Article) Related Research:
