中文摘要：

研究了循环荷栽作用下铝合金轴压构件的力学性能，并与钢轴压构件进行比较。采用通用有限元分析软件ANSYS对铝合金轴压构件的滞回性能进行有限元分析。分析方法考虑了材料非线性、几何非线性和初始缺陷的影响。根据计算结果，得到了6061-T6铝合金、印61-T4铝合金和Q235钢3种材料轴压构件的滞回曲线、恢复力骨架曲线和刚度退化曲线，并进行了比较研究。分析结果显示，铝合金轴压构件的滞回性能与低碳钢轴压构件较为类似，并受到材料本构关系的显著影响。

英文摘要：

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 6061 -T6 aluminium columns, 6061 -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.
