Plasticity in steel is characterized by an appreciable amount of plastic flow which precede strain-hardening. Out- of plane flexural rigidities of steel plates stressed into the plastic flow range at the instance of plate buckling were evaluated in the previous paper. This study deals with buckling of steel plates with its four edges simply supported under biaxial normal stress. Buckling stress and strain of steel plates under biaxial compression are examined in the elastic, plastic flow and strain-hardening range by the moduli to relate the flexural rigidities derived in the previous paper. It is shown that the values of flexural rigidities are fairly influenced by the difference of stress point on von Mises'yield locus and then the behavior of plate buckling is also fairly influenced by it.
