摘要

应用规范中的相关设计公式，考虑了加筋薄壁冷弯型钢受压构件和受弯构件局部屈曲和变形屈曲的差异。然而，对于未加筋或加筋不够的构件，扭曲模态和局部屈曲模态的区别是相当混乱的。

Local-distortional and Overall Interactive Buckling of Unstiffened Open Cross-section Thin-walled Steel Members

The difference between local and distortional buckling of thin-walled cold-formed steel sections with stiffened elements, of both compression and bending members are take-in-to consideration applying relevant design formulas available in the codes. However, for unstiffened elements or for those not stiffened enough, the difference between distortional and local buckling modes is quite confusing.
