shear force diagram

The vertical beam shear and the bending force calculation; The Plotting of the Shear Force Diagram by the Graphic Method

用图解法作梁的剪力图和弯矩图

Comparing with the traditional method of drawing internal force chart, this method is very simple, it is easy to master and easy to check-up. It unifies drawing shear diagram and bending moment chart using the differential coefficient connection between load collection degree and internal force.

与传统绘制内力图的方法相比，该方法不仅简捷、直观、易于掌握、便于验算，而且和教材中利用载荷集度与内力之间的微分关系画剪力图、弯矩图，形成有机的统一。

质点路线法多跨梁剪力图的快速绘制方法

The plot of the Shear Force Diagram and Bending Moment Diagram is not only important but also difficult for the students to learn in the course of Mechanics of Materials. The Graphic Method introduced in the paper is easy for students to master.

绘制剪力图和弯矩图是《材料力学》课的重点和难点，用本文论述的图解法作梁的剪力图和弯矩图学生易于掌握。

This method can not only be used to draw shear force diagram quickly, but also to determine the shear sign automatically, and to verify the reaction force of multi-span beam.

该方法不但能快速绘制剪力图，而且自动确定剪力符号，兼可对多跨梁的支座反力进行校核。
