When reinforced concrete members are subjected to bending moment, rotational deformation occurs in their ends. That deformation is generally considered to result from a slip of longitudinal bars, and some methods to estimate the rotational angle have been proposed. On the other hand, although a phenomenon that the members subside into the beam-column joints is observed, it has not been investigated. In this paper, it is insisted that the deformation results from a reciprocal action of the subsidence and the slip. A model to estimate the rotational angle considering the subsidence is proposed, and it gives good agreement with test results.
