摘要
通过对剖分 T型钢局部屈曲相关性的分析 ,指出了规范中对其腹板宽厚比限值过于保守。考虑了翼缘对腹板提供约束 ,在对规范 GBJ1 7-88中的剖分 T型钢截面的计算结果上 ,提出了腹板宽厚比限值的计算公式 ,用于剖分
By study of interactive buckling in T-style steel, it is shown that the current specifications are too conserving for the webs' ratio of width to thickness. Based on the calculated results of cut T-style steel elements in axial press, in GBJ 17-88, including the webs' constraint by the flanges, a rational limited ratio of width to thickness in web for design is given.
