Shear - XZ

The XZ shear is orthogonal to the XY shear described in the previous section. The forces and moments causing the shear can be seen in 図 1.
図 1. XZ Shear Forces and Moments


The forces and moments are calculated by:
図 2.
F z 1 = f z ( u z ) + C z u ˙ z
図 3.
F z 2 = − F z 1
図 4.
M y 1 = l F z 2
図 5.
M y 2 = M y 1

Where,

u z = u z 2 − u z 1 + l ( θ y 2 + θ y 1 2 )

f z ( u z ) is the function defining the force-displacement relationship.
