There are stresses of many directions in the structures, while few studies on the failure criterion of concrete. It may failure be said, it is not given how to find the yield or failure strength under combined force, as bending moment, axial force, shearing force, ets. We have had a fundamental study on the failure function of concrete to make clear the ultimate strength of concrete members. In this part, it is assumed this function is given J_2^<1/2>+αJ_1=k^*, and it is discussed how to apply for the limit design. We obtain α=0.567, k=0.847 f_c, using plastic potential theory referring to the data of past experiments. * J_2^<1/2>={(σ_1-σ_2)^2+(σ_2-σ_3)^2+(σ_3-σ_1)^2}^<1/2>, J_1=σ_1+σ_2+σ_3 σ_1〜σ_3 : principal stresses.
