In recent years, the application of multilayered resin materials for repair of deteriorated concrete structures is widening and also attracting technical attention. In engineering design of multilayered resin materials, it is important to evaluate the mechanical behaviors of interface among layers and concrete surface during various stages under service conditions as well as providing adequate chemically and physically stable bonding between them. This paper discusses not only the determination of functional needs which vary according to the performance requirements, such as shear stress in the adhesive layer, shear stress concentration at end of adhesive joint, etc., required for application of multilayered resin materials to repair of deteriorated concrete structures, but also a design concept of the multilayered resin materials based on a few indexes which represent their mechanical behaviors.
