超薄冷弯型钢C形截面构件轴压承载力分析

摘要

Analyzes the influence of various wall thickness on the C-shaped section component’s axial pressure loading capacity of ultra-thin cold bending section steel,adopts the finite element software ABAQUS,to have the linear buckling analysis of the components,and calculates the ulti-mate bearing capacity of the cold bending thin-wall steel components with various thicknesses,and have some meaningful conclusion.%分析了壁厚不同对冷弯薄壁型钢 C 形截面轴压构件抗压承载力的影响，运用有限元软件 ABAQUS 对构件进行了线性屈曲分析，并结合有限条程序 CUFSM，通过直接强度法计算了不同厚度冷弯薄壁型钢构件极限承载力，得出了一些有意义的结论。
