In this paper, assuming that the embedding deformations under steel plates and dowels were almost equal to the deformations of damage zone in these joints, the evaluation methods of stiffness of tensile-bolted joints and dowel-types joints based on Strongest link model were proposed. To inspect the proposed methods, we compared and verified experimental and calculated results. The experimental and calculated values by the proposed methods were in good agreement and the effectiveness of the proposed methods was shown.
