Analysis on stability performance of aluminium columns under cyclic loading
Translated Abstract
The mechanical properties of axial compression aluminium members under cyclic loading were studied and compared with those of steel columns.A finite element analysis method based on FEA software,ANSYS was employed to conduct a theoretical study on hysteretic behaviour of alu-minium columns,which involves the effects of material nonlinearity,geometrical nonlinearity and in-itial imperfection.The hysteretic curves,reversal skeleton curves and stiffness degradation curves of 606 1 -T6 aluminium columns,606 1 -T4 aluminium columns and Q235 steel columns under axial cyclic loading were obtained and compared.The results show that the hysteretic behaviour of the aluminium columns is similar to that of the low carbon steel columns and is significantly influenced by constitutive relationship.
