| Abstract: | The Secant formula for square cross-section columns composed of two different materials is presented. The validity of the formula for concrete-filled square steel tubular columns under axial compression is proved by experiments. Furthermore, the analytical expression for computation of the ultimate loading of concrete-filled square steel tubular columns under eccentric compression is obtained by modifying the distribution of the cross-section stress. |
