In this paper, an analytical interfacial stress analysis is presented for cracked reinforced concrete beams bonded with thin plates and subjected to symmetrical tensile forces and/or end bending moments. A representative element between two contiguous cracks is considered under the assumption of plane stress. By means of the principle of minimum complementary energy, the analysis provides a closed-form solution that can be used easily to predict the stress distributions near the cracks in the beams. Numerical results from the present analysis are presented to study the effects of both material and geometric properties of the beams on the distributions of the interfacial stresses.
