This study deals with the reinforced concrete columns, which are designed according to the 1962 AIJ R/C building code and are subjected to antisymmetric bending shear until flexural or shear failure. The main objectives of this paper are (1) to investigate the two-dimensional deforming modes of the column, and (2) to clarify the relationship between the deflection angle of the column and the crack displacement, ie, the relative displacement of concrete at the both sides of the flexural or shear crack. After the diagonal shear failure, the averaged transverse strain at the middle part of the column was uniform and remained almost constant during the cyclic loading as shown in Fig.30. There existed a definite relation of Eq.(61) between W_y, and R_<max> (maximum deflection angle so far). In case of flexural failure, there existed a relationship of Eq. (59) between the crack width W and the current deflection angle R, where g was the distance from the neutral axis to the measuring location of the crack width.
