钢梁腹板弹塑性屈曲强度的试验研究

EXPERIMENTAL STUDY ON ELASTOPLASTIC BUCKLING STRENGTH OF WEB IN I-SECTION GIRDER

  • 摘要: 对工字钢梁腹板在弯曲应力作用下的弹塑性屈曲承载能力进行了试验研究,并与理论计算结果进行了对比分析,同时,研究了纵向加劲肋对腹板屈曲系数的影响。提出了腹板高厚比的合理取值,对现行国家标准《钢结构设计规范》(GBJ17)的有关条款进行了讨论。

     

    Abstract: The elastoplastic buckling strength of the web in I-section steel girder under pure bending was studied experimentally, the comparison between experimental and theoretical results was made. The influence of stiffness of longitudinal stiffener on buckling coefficients of the girder web was analyzed. And the reasonable ratios of height to thickness of the web were given and some items of the Chinese "Code for Design of Steel Structures" were discussed.
