摘要:

对于钢结构工程中的组合梁,利用有限元技术,分别计算了不设置腹板加劲肋与设置腹板加劲肋时,梁截面上的最大等效应力分布情况。得出了设置腹板加劲肋可以显著降低偏心荷载作用下梁截面上应力峰值的结论,并提出了在设计时应注意的具体事项。

关键词: 组合截面梁, 偏心荷载, 有限元, 应力, 变形

Abstract:

In this paper, when the beam was applied with eccentric force, the finite element analysis technique was used to calculate the maximum stress peak in the combined beams section. For the combined beams of the steel structure engineering while the beams are mounted and are not mounted web stiffener, and the results were that the stress peak in web stiffener of the beams section can be reduced remarkable, finally, it provided the detail items for the designing of beams.

Key words: combination beam, eccentricity force, finite element method, stress, deformation.
