Fiber reinforced plate (FRP) possess the advantages of high strength, light-weight, high corrosive resistance, etc. Recently, FRP materials have been widely used for the strengthening and rehabilitation of concrete structures. Present paper is based on truss model and compression field theory in equilibrium and compatibility. Present paper will develop two kinds of theoretical models to describe the shear behavior of the reinforced beam strengthened by FRP according two different constitutive laws of concrete. The one is endrochronic constitutive equations for concrete developed by Lu and Wu and the other is softened stress-strain relationship of concrete suggested by Vecchio and Collins. Also, several different conditions are discussed. The theoretical results are compared with experimental data. The results are satisfactory.
