There is an ongoing research proeject at the University of Texas at Arlington on repairing full- scale prestressed concrete bridge girders exposed to simulated lateral impact damage with carbon fiber reinforced polymers (CFRP). This research aims to utilizie the full strength of the CFRP by proposing and testing various types of anchorage systems.

The project has four phases:

  • First Phase: Construction of 5 girders, then all of them will be pre-damaged by saw-cutting through the concrete and one of the prestressing strands.
  • Second Phase: Repairing four of them using CFRP and an achorage system.
  • Third Phase: Conducting of four-point flexural test.
  • Fourth Phase: Finite element model will be developed to verify the results of the experiment.
