be used to support a split-level floor. This application is commonly used in theaters and in private housing for aesthetic reasons. The stepped beam provides additional need for reinforcement detailing to fulfill the stress concentration at the stepped joint. The well-known advantages of fiber-reinforced polymer (FRP) composites over other strengthening materials make them a good choice for civil engineering applications. These materials can be designed and used in the form of laminates, rods, dry fibers (sheets) adhesively bonded to the concrete, wet lay-up sheets mounted on the surface, or near surface mounted bars or laminate strips in the concrete cover [1]. Over years, a large numbers of studies on the behavior of CFRPstrengthened beams have been conducted to have a better understanding for their behavior under different loading conditions along with to develop the best technique of applying the CFRP fabric sheets and/or strips. Many drawbacks associated with the application of the CFRPs attributed to the characteristics of currently available commercial CFRP strengthening systems. Although CFRPs have high strength, they are very brittle. When loaded in tension, FRPs exhibit a linear stress–strain behavior up to failure, without exhibiting a yield plateau or any indication of an impending failure. As FRPs behave differently than steel, they consequently suffer from a significant loss in beam ductility, particularity when CFRPs are used for flexural strengthening of RC
