Experimental study on C-section columns and built-up I-section columns was conducted. The cross-sectional dimension, the thickness and the length of the tested members were varied. Noticeable interactive buckling modes were observed for built-up columns in the test. A novel direct strength method was proposed for built-up I-section column.
