Based on the common calculation methods of normal section bearing capacity of steel reinforced concrete (SRC) columns with I-shaped steel, SRC columns containing T-shaped steel are presented and their mechanical properties and failure modes are analyzed. Combining with actual engineering and current national codes, the calculation methods and formulas of ultimate moment capacity of this column are proposed and heights of the concrete pressured region in two different situations are compared, by which it can be seen that SRC columns are easier to form large eccentric compression failure when the big flange is nearer to axial force N .The bearing capacity of one SRC column with T-shaped steel is checked using above proposed formulas and the calculation results agree well with the experimental data, and finally this numerical example shows that the suggested method has good precision and reasonable application.
