研究了循环荷载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、6061-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。
研究瞭循環荷載作用下鋁閤金軸壓構件的力學性能,併與鋼軸壓構件進行比較。採用通用有限元分析軟件ANSYS對鋁閤金軸壓構件的滯迴性能進行有限元分析。分析方法攷慮瞭材料非線性、幾何非線性和初始缺陷的影響。根據計算結果,得到瞭6061-T6鋁閤金、6061-T4鋁閤金和Q235鋼3種材料軸壓構件的滯迴麯線、恢複力骨架麯線和剛度退化麯線,併進行瞭比較研究。分析結果顯示,鋁閤金軸壓構件的滯迴性能與低碳鋼軸壓構件較為類似,併受到材料本構關繫的顯著影響。

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.
