Abstract
    The use of externally bonded composite materials for strengthening reinforced concrete structures has received considerable attention in recent years. Since, concrete is a relatively fragile material and will fail when subject to the influence of many factors whose origins can be mechanical, physicochemical and accidental or related to the design and miscalculations. The bonding of FRP plate to reinforced concrete structure, appeared in the middle of the fourtwenties years, proves to be a promising and fully justified technique. In this paper, an analysis and modeling of the concentrations of interfacial stresses in a damaged reinforced concrete beam strengthening in bending by an imperfect FGM plate, was presented, based on a development of a mathematical formulation taking into account the theory of beams. The theoretical predictions are compared with other existing solutions. This research is helpful for the understanding on mechanical behaviour of the interface and design of the imperfect FGM – damaged RC hybrid structures.
