| 摘 要： | 应用变形能法对矩形、圆形、工字形截面梁在剪力作用下的弯曲变形进行了定量分析比较。结果得出,剪力对梁弯曲变形的影响与梁的截面形状、跨度、截面高度等因素有关。认为在有些情况下,剪力对弯曲变形的影响相当大,不能略去,进而为合理设计梁的结构提供科学可靠的理论依据。

| Abstract: | Application of strain energy method for quantitative analysis and comparison on the bending deformation of rectangular, circular, I-section beam under shear force. The results of beam bending, shear and the influence of beam section shape, span, section height and other factors. In some cases, a considerable influence on the shear force,bending deformation can not be omitted, so as to provide reliable scientific theory for the reasonable structure design of the beam. |
