| 摘 要： | 采用有限条法分别对轴心受压、受弯卷边Ｚ型钢构件的弹性相关屈曲作了分析，推导出板件屈曲系数表达公式，并阐明按现行《冷弯薄壁型钢结构技术规范》（ＧＢＪ１８－８７）计算轴压卷边Ｚ型钢构件偏于不安全，而对于受弯构件又过于保守，最后给出了计算Ｚ型钢有效宽度的建议公式。

| Abstract: | Making use of finite strip method to analyse respectively the interactive buckling of Z-section members with stiffened edges under axial compress and tending in this paper. paper. formulations of buckling coefficients are induced. It is revealed that according to the provisions of the GBJ18-87 specification, the calculation of members aren't safe under axial compress, and conservative under tending. The recommended formulations of the effective width are presented at the end of this paper. |
