The experimental data of the previous studies on interior beam-column subassemblages without transverse beams and made of normal weight concrete of 120-500 kg/cm^2, are verified by the previous equations for ultimate shear strength capacity. This study is carried out to develop the equations for more accurate prediction on the strength capacity and also the failure mode. The following statements can be made. (1) It is pointed out that the ultimate shear strengths of joints mainly depend upon the compressive strength of concrete and the shear resistance mechanism is appeared to be the inclined strut mechanism. (2) The equations [(4a)〜(5b), (8a)〜(9b)], for more accurate predictions than before, of ultimate shear strength of beam-column subassemblages in case of joint shear failure (S) and joint shear failure after yielding of beams (FS) are developed. (3) The more accurate methods [(10a)〜(10d)], for predicting the failure modes S, FS, F (beam flexural failure mode) in the subassemblages, are developed.
