Through applying MSC.Marc nonlinear finite element software,\nthis research is to explore the ductility performance of steel reinforced\nconcrete T-shaped columns under reciprocating loading. The result shows\nthat the MSC.Marc calculation results are quite consistent with the\nexperimental data, and can objectively reflect the mechanical properties of\nsteel reinforced concrete special-shaped columns. These mean that the\nMSC.Marc software can be used for performing simulation analysis on the\nsteel reinforced concrete special-shaped column hysteretic performance.\nThrough changing the axial compression ratio, shear span ratio and load\nangle to research the ductility performance of steel reinforced concrete\nT-shaped columns under reciprocating loading, the main conclusions are as\nfollows: The bearing capacity of steel reinforced concrete t-shaped cross\nsection column decreases with the increase of shear span ratio;\ndisplacement ductility decreases with the increase of axial compression\nratio; mechanical properties of the web load are superior to the ones of the\nflange load.
