This paper deals with the theoretical analysis of elasto-plastic buckling of steel plate under uniaxial repeated loading. According to the principle which appeared in this transactions No.125 July 1966, critical strain (ε_<ck>)_p in plastical domain has the following form (3.16) on simple supported plate under increasing load. The import of this equations are shown in Fig 4. In this result, (ε_<ck>)_p on the plate under repeated loading has the following form (3.16), too. And the plysical import of this case are shown in Fig. 6. In the next, it is consider that the steel plate is stable in elasto-plastic domain under always increased compressing from σ=0 : ε=0, the condions of this stable given by the table 1, assuming that the strain of steel plates at the end of the flat yielding zone ε_B 1.4%.
