| 摘 要： | 根据荷载集度与剪力、弯矩之间的导数关系,找出了绘制内力图的规律,应用此规律画剪力图和弯矩图不必列内力方程,只需依据梁在不同荷载作用下剪力图及弯矩图的图形特征计算出控制截面的内力值,即能简便、快捷地画出内力图。

| Abstract: | Based on derivative relationship between load sets,shearing force and bending moment,the rules are discovered for drawing internal force diagrams.With the rules,internal equations are not necessary for drawing shearing force diagrams and bending moment diagrams and only the numerical value of internal force for the controlled sections is needed calculated according to the graphical features of shearing force diagrams and bending moment diagrams for beams under different loads.That is the way to drawing inte... |
