Steel-Free Hybrid Reinforcement System for Concrete Bridge Decks
A research project was initiated to develop a nonferrous hybrid reinforcement system for concrete bridge decks by using continuous fiber reinforced polymer (FRP) rebars and discrete randomly distributed polypropylene fibers. This hybrid system may eliminate problems related to corrosion of steel reinforcement while providing requisite strength, stiffness, and desired ductility, which are shortcomings of FRP reinforcement system in reinforced concrete. The test results showed that with the addition of fibers, structural performances of the system are improved. Although polypropylene fibers do not increase the ultimate bond strength, they provide enhanced ductile bond behavior. Also, with the addition of fibers, the flexural behaviors are improved with the increase of the ductility index m by approximately 40%, as compared to the plain concrete beams. In addition, with the addition of polypropylene fibers, the durability of the system was improved. Furthermore, some design recommendations are proposed based on analytical models and test results.
