| Abstract: | A test on the steel reinforced concrete(SRC)column with normal cross?section and circular steel tube is conducted According to the test results,a theoretical formula for the limit value of axial compression ration of SRC is obtained It is also based on the equilibrium condition of internal forces in the case of critical failure It is the case that a practical formula is put forward The formula is linked up with the limit values of axial compression ratio of reinforced concrete columns provided by the recent code An example is also presented to illustrate the usage of the formula |
