Abstract:

Corrosion of steel rebar is the leading source of deterioration of concrete transportation structures. Fiber reinforced polymer composites (FRP) are potentially a more durable alternative, but the unique properties of FRP mean that simply replacing steel bar with FRP bar may not realize the full benefits of FRP. In this exploratory study, two alternative reinforcement geometries were designed, fabricated and tested in small concrete beams. The alternative reinforcements made use of helical and wave geometries intended to induce compression in the neighboring concrete when the FRP reinforcement experienced tension due to flexural loading. The testing compared the performance of the beams with the alternative FRP reinforcement geometries to beams with straight FRP bars of approximately equal cross-sectional area.
