The aim for this study is to clarify the shear stress transfer mechanism on the concrete crack surface. In the previous paper, it was confirmed that the stress softening was occurred on local crack surface by the authors experiments. However, the shear stress transfer models considering this phenomenon haven't been constructed. Therefore, it is needed to be proposed such a shear transfer model, and authors tried to do it. The proposal model is based on the contact theory in two- dimension. Moreover this model and other previous models are compared with the experimental curves in order to be verification of the models adaptation. In this paper, the formulations of the proposal model and results of comparing are presented . As the result, it is concluded that the proposal model can fit authors experimental results much better than any other previous models.
