| 摘 要： | 通过对不同长度C型和Z型截面冷弯薄壁型钢构件进行屈曲临界荷载计算,将有限条法(FSM)计算结果和有限元法(FEM)计算结果进行对比,分析了有限条法计算误差产生的原因;并且归纳了有限条法在冷弯薄壁型钢构件屈曲分析中的适用范围。算例分析表明,有限条计算结果中只有长细比较大且发生一个半波屈曲的情况才与实际相符合。

| Abstract: | In this paper, the error of finite strip method is analysed after calculating the critical buckling load on different length of C section and Z section cold-formed steel members by finite strip method and finite element method separately.Then the suitable range of the buckling analysis of cold-formed thin-walled steel members by finite strip method are concluded.The example show that only the members with only one half wave and large slenderness ratio are in accordance with the practice. |
