摘要
引用国外的试验结果,根据规范中轴心受压构件稳定承载力计算公式,反算出冷弯薄壁卷边角钢稳定性系数,得出φ--λ曲线,并利用数值方法拟合出一组计算公式。通过理论分析比较,建议的公式是简洁的、合理的。
Citing the foreign test results,according to the axial stability capacity formula in the code when the cold-formed thin-walled lipped angle subjected to concentrated bearing load,φ-curve was got and fitted a set of calculating formula using the numericals were also fitted calculating method.Through theoretical analysis and comparison,the proposed formula is simple and reasonable.
