The deformation and strength of adhesive shaft joints were investigated analytically and experimentally. The meal shafts were adhesively connected with a coupling and epoxy resin. The outer diameters of the coupling and the shafts were identical. The joint configuration was straight through the shafts and the coupling. The strain and stress distribution of the adhesive straight shaft joints were calculated for various dimensions using the finite element method. It was shown that stress concentrations occurred in the adhesive layer and the adhesive interface near the edges of the coupling. The strains measured by the strain gauges on the surface of the straight shaft joint were in close agreement with the calculated results. The strength of the joints was predicted by applying three kinds of strength laws of GFRP, carbon steel, the adhesive layer and their interfaces to the stress distribution. The predicted strength for initial failure loads of the adhesive shaft joints under combined loads was in good agreement with the calculated results.
