摘　　要：不少国家已把利用焊接工字梁腹板的屈曲后强度继续承受荷载列入钢结构设计规范。但（钢结构设计规范）（ＧＢＪ１７—８８）还没有这方面的条文规定。通过对焊接工字梁腹板屈曲后强度的理论分析及试验研究，得出了一些对规范修订有重要参考价值的结论。The pet-buckling strength Of web plate of I-section girder is considered to resist the shear force in many other countries' code for design of steel structures, while it has not been considered in the Chinese code GBJ17-88. For the code revising, some important conclusions have been drawn through the theoretical analysis and experimental research of the post-buckling strength of web plates of I-section girder.
