摘要
采用ANSYS有限元软件,对冷弯薄壁加劲卷边角钢轴压构件的畸变与局部相关屈曲性能进行模拟分析。研究不同卷边宽度对构件的屈曲模式及临界荷载的影响,以及不同厚度对构件的畸变与局部相关屈曲临界荷载及经济系数的影响。结果表明:卷边宽度对构件的屈曲模式及临界荷载有较大影响,对比不同卷边宽度下各构件的临界荷载值,得出卷边宽度与肢长比在6/25左右较合理;板件厚度对于畸变与局部相关屈曲临界荷载有较大的影响,对比不同板件厚度下各构件经济系数的变化,得出板件厚度与肢长比在7/150左右较合理。
The performance of distortional- local interactive buckling on stiffening lipped angle steel members under axial compression is studied in the thesis by using ANSYS finite element software. The effect of different edge width on buckling mode and critical load and the effect of different panel thickness on distortional- local interactive buckling critical load are studied. The results indicate that：Edge width has great effects on distortional- local interactive buckling mode and critical load of the component. The critical load value under different edge width is contrasted to get a reasonable edge width and limb length ratio range; the panel thickness has great effects on the critical load of distortional-local interactive buckling. The change of economic coefficient under different panel thickness is contrasted to get a reasonable panel thickness and limb length ratio range.
