The authors described buckling strength and post buckling strength of thin steel plate with aspect ratio of 1.0 partially supported by steel frames in the previous paper. In this paper, the buckling stress of the plate of aspect ratio between 1.0 and 3.0 used by the bracing model is discussed. The approximation formula of the buckling strength is proposed by using the tensile-compressive bracing model. The result are compared with the buckling mode analysis and the geometric nonlinear analysis by FEM. The approximation formula of the post buckling strength of thin steel plate combined with steel stiff frame is proposed in consideration of stress distribution and yield condition. Also the relationship between the bending rigidity of the steel frame and post buckling strength of the steel plate is examined.
