The rigidity and deformation characteristics of an adhesive lap joint subjected to a lateral bending load have been examined both theoretically and experimentally. The deformations were analyzed using the theory of a beam on an elastic foundation. They coincided well with the experimental results. The deformations and rigidity of adhesive joints can be well estimated using the beam theory. Effects of the length of the bonded part and the thickness of the adhesive layer on the rigidity were clarified and a design criterion of adhesive joints was proposed. Furthermore, experiments with respect to the rigidity of a bolted joint were carried out and the results were compared with those of the adhesive joint. It was observed that, the rigidity of the adhesive joint was greater than that of the bolted joint when the thickness of the adhesive layer was thin, and that greater load could be applied to the adhesive joint than to the bolted joint.
