The results of the study undertaken to understand the interfacial stresses and debonding failures in plated beams are presented. A novel theoretical solution of interfacial stresses has been developed that is applicable to any loading, initially considering axial and flexural deformations in the beam and plate within the linear elastic range. The solution has subsequently been enhanced to include the effect of shear deformation of the adherends by adopting an approximate displacement field method coupled with Timoshenko's beam theory. The accuracy is further improved by developing a rigorous solution fully based on Timoshenko's beam theory, leading to the solution including the effect of adherends' shear deformation on both interfacial shear and normal stresses. A structural mechanics formulation for a fiber-reinforced polymer (FRP)-to-concrete bonded joint between two adjacent cracks is developed to characterize the behavior of IC debonding failure.
