| Abstract: | The cold-formed square steel tube columns with different width-thickness ratios are analyzed by FEM.Whose response,the distribution of stress and strain under axial loads are examined. It is concluded that their full sectional ultimate strength is decreased with the increase in width-thickness ratio. |
