  buckling of web
Failure of the elements has occurred by gradual continuous irreversible lateral buckling of web and flanges, and by plasticity of the decisive area.
      
Buckling of web or roof rafter due to column being shifted to the left of stiffener during erection.
      


When a welded I-section plate girder is subjected to bending or shearing,buckling of web in elastic range will be restrained by flanges.Analysis madewith Gatekin's method using characteristic function of buckling of strut as a form function,has shown that the restrint of the flange depends upon the size of the flange and the web.

在纯弯或纯剪分别作用下的工字形焊接板梁,在弹性范围内腹板屈曲时,翼缘会对腹板起约束作用。通过采用柱稳定特微函数的形函数,用伽勒金法计算表明,其翼缘约束作用的大小,是与翼缘和腹板的尺寸有关。

The current code presents a complicated procedure for calculating the strength of beam columns with thin walled H section considering the local buckling of webs.This paper calculates the interactive relations between the axial force and bending moment based on the current code procedure.It is found that code CECS102:98 gives an unsuitable interactive curve when the web slenderness λ p is greater than 3 87.This paper presents a simplified formula for the interactive curves based on AISI...

The current code presents a complicated procedure for calculating the strength of beam columns with thin walled H section considering the local buckling of webs.This paper calculates the interactive relations between the axial force and bending moment based on the current code procedure.It is found that code CECS102:98 gives an unsuitable interactive curve when the web slenderness λ p is greater than 3 87.This paper presents a simplified formula for the interactive curves based on AISI specification,which has a very good accuracy compared with the code method.For monosymmetrical H sections,the tensile side of the section may yield first,the current specification pays no attention to this problem at all.A simple formula is also put forward for this case.

通过大量的计算 ,对现行《门式刚架轻型房屋钢结构技术规程》中的考虑腹板局部屈曲的薄壁工形截面压弯强度计算进行了分析。指出了《规程》中的缺陷及其改进方法 :一是对单轴对称截面较大翼缘受压的情况 ,除了验算受压区屈服的情况外 ,还应补充验算受拉翼缘先屈服的情况 ,作者给出了具体的验算公式。二是用《规程》中的方法进行计算时 ,只在轴力作用下 ,腹板宽厚比 (hw/tw) fy/2 35>2 1 7时 ,ρ <0 ,即整个腹板受压区都失去作用 ,这与实际情况不符合。对此 ,使用美国AISI规范公式进行了计算 ,给出了以美国AISI规范公式为基础的精度良好的简化近似公式 ,以供参考使用。

Local load,or patch load,which is applied perpendicular to the flange of I-girders and transferred to the web,occurs in various situations in steel structures.A finite element analysis was carried out to investigate the elastic buckling of webs in I-girders under patch load.Elastic buckling coefficients considering the rotational restraints at the flange-web juncture were obtained and a formula with good accuracy and clear physical meaning was proposed.

钢结构工程中经常遇到一定宽度的均布荷载通过翼缘传递到腹板上的情况,这种荷载称为局部荷载。本文对工字形梁腹板在局部荷载作用下的弹性屈曲进行了有限元分析,得到了不同宽度的荷载作用下工字形梁腹板的弹性屈曲系数,着重考虑了翼缘的转动约束对腹板屈曲的影响。通过数据拟合得到了物理意义明确、精度很高的计算公式。
