Using the assumptions of stress-strain curve and of strain distribution, we computed the ultimate bending strength about 576 models of reinforced concrete columns by fiber model method in each principal and diagonal axis of cross section under the constant axial force. On the basis of these values (called base data), we propose the equations which can evaluate the ultimate bending strength about principal and diagonal axes. The form of the proposed equations are as follows. Mu=ξ/(σ_y^a・F_c^β・D_o^3) ξ=A・η^3+B・η^2+C・η D, η=N/(F_c・D_o^2), β=β_1・η+β_2・σ_y+β_3 Where α, β_1, β_2, β_3, A, B, C, D are expressed only by total reinforcement ratio. The values, calculated on these equations, are good approximation to the base data and correspond to the results of experiment.
