| 摘 要： | 在已有弹性相关屈曲成果的基础上讨论了现行规范（ＧＢＪ１８—８７）规定的适用性，又对受弯的卷边槽钢作了有限条法相关屈曲分析，阐明受弯构件中的卷边翼缘按现行规范计算其有效宽度偏于保守，在卷边尺寸适当的情况下可以考虑按两边支承板对待。

| Abstract: | Making use of published materials of interactive buckling, the feasibility of the relevant provisions of the current specification GBJ18-87 has been examined. Moreover, basing on a finite strip calculation performed by the authers on c-section flexurel members, it is revealed that the provisions of theGBJ18-87 specification are too conservative for edge-stiffened flanges. These flagges with adequate edgestiffener may be considered as equally strong as plate elements supported on both longitudinal edges. |
