薄壁构件在轴向受压荷载作用下很容易由于屈曲而失效,但是冷弯薄壁型钢构件的屈曲又是一个复杂的过程。在此用有限条法分析了卷边C型截面钢构件的局部屈曲性能,较真实地反映了其受力的实际情况,得出了卷边C型截面钢构件各个截面参数变化对屈曲的影响。
Thin-walled members are easily failure due to buckling under axial compression load, but buckling of cold-formed thin-walled steel members is a complicated process. In this paper, the local buckling behavior of curled C-section steel members is analyzed by finite strip method, and the actual situation of the curled C-section steel members is more accurately reflected. The influence of various cross-sectional parameters of curled C-section steel members on buckling is obtained .
