Through applying MSC.Marc nonlinear finite element software, this research is to explore the ductility performance of steel reinforced concrete T-shaped columns under reciprocating loading. The result shows that the MSC.Marc calculation results are quite consistent with the experimental data, and can objectively reflect the mechanical properties of steel reinforced concrete special-shaped columns. These mean that the MSC.Marc software can be used for performing simulation analysis on the steel reinforced concrete special-shaped column hysteretic performance. Through changing the axial compression ratio, shear span ratio and load angle to research the ductility performance of steel reinforced concrete T-shaped columns under reciprocating loading, the main conclusions are as follows: The bearing capacity of steel reinforced concrete t-shaped cross section column decreases with the increase of shear span ratio;displacement ductility decreases with the increase of axial compression ratio; mechanical properties of the web load are superior to the ones of the flange load.
