对工字钢梁腹板在纯弯作用下的弹塑性屈曲承载能力进行了理论计算和试验研究，并进行了对比分析，着重研究了纵向加劲肋刚度对腹板屈曲系数的影响－ 对现行《钢结构设计规范》（ＧＢＪ１７ － ８８） 的有关条款进行了讨论－
The elasto-plastic buckling load-carrying capacity of I-beam webs under pure bending was calculated theoretically and experimentally, and comparative analysis was carried out. The effect of stiffness of longitudinal stiffeners on the buckling coefficient of webs was studied emphatically. The relevant provisions of the Steel Structure Design Code (GBJ17-88) were discussed -
