Comments
Element identification numbers must be unique with respect to all other element identification numbers.
The X-axis of the markers M1 and M2 should always be along the axis of the beam.
The moments of inertia are defined as follows:
The beam coordinates must be aligned with the principal axes of the cross section.
The transverse shear stiffness in planes 1 and 2 are (K1)AG and (K2)AG, respectively. If a value of 0.0 is used for K1 and K2, the transverse shear flexibilities are set to 0.0 (K1 and K2 are interpreted as infinite).
