The paper presents an experimental study on shear behavior of RC beams retrofitted with Uni-Directional Narrow Fabric to improve seismic performance. Experimental parameters include the type of fiber, spacing of the fiber, and the ratio of transverse reinforcement. Also, Static loading test was performed on twelve shear-critical specimens. An experimental result were analyzed to investigate the contribution of shear strength and failure modes of the specimens retrofitted or strengthened with Uni-Directional Narrow Fabric compared to the non-retrofitted the specimen. In order to derive the shear strength model according to the spacing of the fiber, the experimental results were compared with the conventional shear strength model of RC elements retrofitted with FRP.
