H, B, ... : Refer to the diagram denoting section dimensions in the dialog box.


Consider Warping Effect(7th DOF)

You have the option to consider the torsional effects. When there is an uneven torsion resulting from the restricted torsional displacement, torque is resisted by St. Venant's torsional shear stress and warping torsion. In cases involving curved members, eccentric loads, or differences between the center of gravity and the shear center, simulating the warping torsion effect using a 1D beam element can provide more accurate results.

When considering the warping effect (7 degrees of freedom), the warping coefficient (Iw), warping functions (w1, w2, w3, w4), and shear deformations due to the twisting moment can be checked in the sectional properties dialog box.
