Abstract
The objective of this paper was to evaluate the suitability of Fiber-Reinforced Plastic (FRP) grids for use as a structural reinforcement in slab-type concrete structures. The behavior of concrete beams reinforced with FRP grids was experimentally investigated. Two different types of FRP grids were tested; the first type used carbon fibers, the second type used a mixture of carbon and E-Glass fibers. The mechanical properties of these two FRP grids were determined. For each of the two types of reinforcement, five concrete beams were tested to failure. The flexural behavior, as characterized by the load-deflection response, was monitored throughout the tests. The results from the flexural tests on FRP reinforced concrete beams showed that the failure mode, measured deflections and ultimate loads were consistent with predictions.
