Concerning the extent of applying composite materials, especially Fiber Reinforced Polymer (FRP), for the rehabilitation of concrete structures, developing a suitable method for analyzing RC elements strengthened with FRP sheets is necessary. In this paper, a micro mechanical approach is introduced for simulating tension stiffening and crack formation in RC members strengthened with FRP. On the basis of the proposed theoretical approach, the spatial average stress-strain relationship of reinforcing bars, FRP and cracked concrete, as well as average crack spacing and width, can be numerically simulated. Verification of the proposed method is carried out through comparison with some experimental results.
