Quick Drawing of Internal Forces Diagram of Bending Member by Area Method

In structural member,bending deformation is the most common form of deformation.It is very important to draw internal forces diagram(shear diagram,bending moment diagram) of bending member quickly and aaccurately whether in the teaching process or in the actual project.The drawing of internal forces diagram of bending member was demonstrated by two examples using the area method.The efficiency of drawing internal forces diagram increased by transforming the internal force of control section calculation to the area of simple geometric shapes calculation in virtue of the integral relations of q(x),Q(x) and M(x),and thus to greatly improve the computational efficiency of engineering design.
