根据焊接工字钢梁主要用于承受弯矩的受力特点，钢梁腹板通常设计得高而薄，这样腹板在屈曲后还有很高的屈曲后强度可供利用，很多国家已把利用腹板屈曲后强度继续承载列入钢结构的设计标准或规范，但我国《钢结构设计规范》GB J17－88还无此方面的条文规定．本文通过对焊接工字钢梁腹板屈曲后强度的理论分析和试验研究，得出一些对规范修订有重要参考价值的结论．

The post-buckling strength of web plate of I-section plate girders 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 GB J17－88.For the code revising,some important conclusions have been drawn through the theoretical analysis and experimental research of the post-buckling strength of web plate of I-section plate girders.
