| 摘 要： | 为了得到单轴压缩杆件考虑几何非线性时的后屈曲特性,介绍Riks弧长法的基本原理,并以工字钢为例,说明Riks弧长法在压杆非线性屈曲分析中的应用.结果表明,考虑初始缺陷后,压杆的屈曲强度大大减小,且屈曲强度对缺陷因子极为敏感.该研究可为单轴压缩杆件的非线性屈曲分析提供参考. |

| Abstract: | In order to get the post-buckling characteristics of rod under uniaxial compression considering geometrical non-linear feature,the basic principle of the Riks arc length method is introduced.The I-steel is taken for example to illustrate the application of Riks arc length method in non-linear buckling analysis of compressive rods.The results show that the buckling strength of compressive rod decrease largely when considering initial defect.The buckling strength is very sensitive to defect factor.The reference can be provided to the non-linear buckling analysis of uniaxial compression rods. |
| Keywords: | non-linear buckle arc length method initial defect load proportion factor |
