| Abstract: | Using the finite element analysis software ANSYS,it was researched that the hysteretic behaviour,strength,deformation,ductility and damage features of the cross-section special-shaped steel columns forced by regular axial compression and cycle moment.And found the main factors effecting the hysteretic behaviour and the influence laws.Which provided a basis for the design and use of the cross-section special-shaped steel columns in strong earthquake defensive zones. |

| Keywords: | cross-section special-shaped steel columns hysteretic behaviour axial compression ratio width-to-thickness ratio |
