摘要
利用ANSYS模型,对Q420高强等边角钢轴压构件的极限承载力进行非线性分析,讨论不同长细比、宽厚比的情况下,截面残余压应力与构件稳定性能的关系,为研究Q420高强角钢轴压构件的整体和局部稳定受力性能提供理论参考。
Stability capacity of axial loaded Q420 high strength steel equal single angle members was analyzed by Ansys model. Relationship between section residual stress and the stability in different flaki- ness ratio and slenderness ratio was discussed. The result provide theoretical references for overall and local stability research of Q420 high strength steel angle under axial compression.
