摘要
对工字钢梁腹板在纯弯作用下的弹塑性屈承载能力进行了理论计算和试验研究,并进行了对比分析，提出了腹板高厚比的合理取值,同时，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 theoretical and experimental study on the elasto-plastic buckling strength of the web in I-section steel girder under pure bending was carried out using energy method and the influence of stiffness of longitudinal stiffener on buckling coefficient of the girder web was analyzed. Good agreement is shown between theoretical and experimental results. The reasonable rations of height to thickness were given and some items of the Chinese national standard 'Code for Design of Steel Structures'were discussed.
