The paper points out the huge difference between the cold-formed thin-wall steel and the traditional thermal rolling structure component in the aspect of the stress,even larger differences in the mechanism under the impact of the axial pressure and the shear bending loading,analyzes the stressed mechanism of the axial pressure stressed mechanism of C-type component cold-formed thin-wall steel,and adopts the finite element software to have the numeric checking,so as to identify the stressed mechanism of C-type component.%指出冷弯薄壁型钢构件在受力上与传统热轧钢结构构件有着很大的不同,尤其是在轴压和剪弯荷载作用下的机理存在较大的差异。在此基础上,针对冷弯薄壁型钢C型构件受力机理展开分析,运用有限元软件进行了数值验证,进而明确了C型构件的受力机理。
