Brief Description of Research Project |
This project is for consideration of the repair of intentionally damaged AASHTO Type III prestressed concrete girders (three locations) to demonstrate the ability of fabric-reinforced-cementitious-matrix (FRCM) and fiber-reinforced polymer (FRP) to restore moment capacity compromised by the loss of four and eight 9.5-mm (3/8-in.) diameter prestressing tendons. In addition, the project includes an extensive material characterization of the strengthening materials. |
Describe Implementation of Research Outcomes |
Results from material characterization, design guidelines, and experimental tests are used to predict and evaluate the flexural capacity of three girders: one control girder, one FRP strengthened girder and one FRCM strengthened girder. Theoretical, experimental, and design capacities are given in Table 6-2 and Table 6-3 of the final report. Based on the results of the material characterization, theoretical analysis, experimental tests, and design analysis performed on each girder, the following observations and conclusions can be determined:
