Abstract	This article introduces two hybrid, pseudo-ductile fiber reinforced polymer (FRP) strengthening systems. Findings from an experimental study to evaluate the effectiveness of these new systems in flexural and/or shear strengthening of reinforced concrete beams are also presented. Currently available commercial FRP strengthening systems have several drawbacks, including brittleness and expense. The two hybrid strengthening systems were designed specifically to avoid the drawbacks of current FRP systems. The first system is a uniaxial fabric consisting of different types of carbon and glass fibers that was designed for use in strengthening reinforced concrete beams for flexure. The second system is a triaxially braided fabric of different types of carbon and glass fibers designed for use in strengthening reinforced concrete beams for flexure and/or shear. Results from the study indicate that both systems show promise in optimizing FRP properties without the drawbacks of typical FRP strengthening systems.
