| Abstract: | The actual ultimate strength of steel tube and core concrete is given according to steel tube yielded, with a view of restriction of outer concrete and hoop bar on steel tube and core concrete. The calculation formula of axial compression capacity for SRC columns with circle steel tube is established. The calculation results agree well with the test results. On the basis of this, the relation between the ratio of radius-thickness and strength is also analyzed. Some advice is proposed for design. |
