How to calculate the shear stiffness of a beam
Lately I began to wonder why I hadn't learned how to calculate the beam shear stiffness in college. I vaguely recalled that the teacher told us the shear stiffness could be omitted in the beam calculation compared to the bending stiffness.
Can anybody show me how to calculate the shear stiffness if it is large enough and cannot be ignored? Like the example shown in the picture below
