The flange height ( b f ) to web length ( b w ) effect on the buckling behavior of a composite column with a channel section was studied. The channel section collumns of b f / b w values 0.3, 0.5, and 0.7 were employed. A theoretical analysis was conducted to decide the dimensions of the columns so that the columns produce as many buckling modes as possible. The buckling mode and critical buckling load for each column were determined from the experiments. Results showed the columns exhibited local buckling and overall buckling (flexural and torsional‐flexural) modes depending on the b f / b w and column length. That is, the flexural buckling occurred only for columns having a b f / b w value of 0.3, while the torsional‐flexural buckling occurred for columns with b f / b w values of 0.5 and 0.7. The results also showed that the local buckling load decreased as b f / b w increased.
