How to Draw the Shearing Force Diagram and Bending Moment Diagram Rapidly

In structural members, the deformation is usually caused by bending or by a combination of bending and torsion. We calculate their strength based on finding the critical section by drawing the shearing force diagram and bending moment diagram that is relatively complex and needs lots of work. Therefore, according to the regulations of shearing force diagram and bending moment diagram caused by different load models, this paper simplifies the process and finds an easy and accurate method.
