| 摘 要： | 冷弯薄壁型钢在轴向荷载作用下主要有3种屈曲模式:局部屈曲、整体屈曲、局部与整体相关屈曲。文中对轴压冷弯C型钢构件的极限承载力进行了数值计算和ANSYS软件模拟,并分析了不同长细比时,局部与整体相关作用对极限承载力的影响。

| Abstract: | For the thin-walled cold-formed steel members subjected to compression,there are three buckling modes: local plate buckling,the overall buckling and the local and overall interactive buckling.The calculation and the numerical simulation by ANSYS software are conducted,the result indicates that the local and overall interactive buckling has famous affection if the member has moderate slenderness ratio,and the ultimate capacity is smaller than the local buckling capacity and the overall buckling capacity. |

| Keywords: | local buckling overall buckling interactive buckling ultimate capacity |
