中文摘要
      在平截面假定和无相对滑移等条件下,基于弹性梁段微元给出了变宽变高波形钢腹板截面剪应力计算理论,认为剪力、弯矩和轴力均会产生剪应力,并且后两者仅仅在变截面产生剪应力.建立了有限元模型,并将传统计算理论和该计算理论与有限元计算结果进行对比,验证了该计算理论的可靠性.
英文摘要
      Under the plane section assumption and the premise that no relative slip exists, a calculation theory of shear stress in the variable depth and width box sections with corrugated steel webs based on elastic beam elements is given. The calculation theory proposes that shear, moment and axial force will all produce shear stress, and the latter two can produce shear stress only in the case of variable cross section. For further analysis, a finite element model is established, and a comparison among the traditional calculation theory, the calculation theory and the results of the finite element model is conducted. The calculation theory is proven to be reliable.
