An analytical study is presented on the post-buckling behavior of angles. The objective of this study is to extract the effect of the local buckling of plate elements on the post-buckling strength. The finite element analysis is conducted, using 20-degree of freedom rectangular plate elements. The computed results showed that the cross sectional change caused by the local buckling reduces the post-buckling strength significantly, provided that the member buckles toward the direction where edges of the angle are compressed. On the contrary, if the member buckles toward another direction, the effect of cross sectional change to the post-buckling strength is rather neglibible. Computed results agreed well with the experiments conducted by Iwai et al.
