摘　　要：波浪腹板工形构件在实际工程应用中,往往由于穿管线等使用功能要求需要在腹板中间开孔。目前,国内外很少看到波浪腹板开孔后抗剪及抗弯承载力研究的相关文献。通过大量有限元数值分析,研究开孔后波浪腹板工形构件截面剪应力的分布及变化,进而通过弹塑性屈曲分析,获得计算其抗剪承载力的拟合公式。此外,还讨论了开孔对波浪腹板梁受弯承载力及挠度的影响,以及开双孔时孔间距的影响。It is common to meet the H-shaped member of sinusoidal webs with openings. Currently, the shear and bend-carrying capacity of H-shaped member of sinusoidal web with circular openings was rarely studied. This paper presents a finite element analysis, resulting in shearing stress distribution and amplitude on the web with opening . Accordingly an equation to predict the shear-carrying capacity of the web with openings was proposed, based on lots of FE numerical results. Finally, the bend-carrying capacity and deflection of the beam with web openings was also analyzed, as well as the influence of gaps between openings.
