It was discussed in the first report that by the Ohno's anti-synmetrical shear loading test on the shear joints with the various types and numbers1 of cotters or teeth-marks, the ultimate strength had depended upon not only the shearing area but also the way of adding force and the figure of cotters or teeth-marks and also by the elastic stress distributions, the destructive cracks had occured towards the principal atresses and there had existed an obvious certain relation between the apparent plastic sphere γ_t and its stress slope Δ on the surface of destruction, furthermore by using these relation, the method of estimating the shear strength of cotters or teethmarks of the complicated shape from the elastic stress distribution had been offered. In the present paper, we will report the experimental results about the forms of distruction and the property of strength of shear joint with 1 to 3 teeth-marks by the various shearing tests with short shear spans, and in these cases there exist the same relation in the previous reports between the apparent plastic sphere and its slope of 「criterion ratio stress of destruction」 curves on the surface of destruction by the elastic stress distributions of all specimens used in the experiments.
