| 摘 要： | 本文用材料力学的分析方法,导出了一个计入剪力时梁的挠曲线的微分方程式。为了估计剪力对梁变形的影响,在集中力作用下梁内剪力用一个单值连续的反三角函数表示。由能量法确定了截面因子数值之后,定量地给出计入剪力时梁变形的分析结果。其结果和弹性力学的结来是一致的。

| Abstract: | In this paper, a differential eqaution for the deflection of beams, including the effect of shear, is derived using the analytical method for strength of materials. To evaluate the effect of shear on deformation of beams, shear in beams under the action of a concentrated load is expressed in terms of a single-valued continuous inverse trigonometric function. After determining the magnitude of the section factor by the energy method, the analytical results of deformation of beams, including the effect of shear, are given quantitatively. And the analytical results in this paper are in coincidence with those in the theory of elasticity. |
