NOTES

The tangent and curvature vectors of the crosssection must be defined to execute SectionBuilder.

In many applications, beams carry large axial forces, such as centrifugal forces, for instance, and the resulting axial stresses affect their torsional behavior. To capture this important coupling effect within the framework of beam models, a nonlinear theory must be developed that takes into account higherorder strain deformations. If ThirdOrderFlag = YES, SectionBuilder will compute the six geometric stiffness matrices associated with the six unit values of the sectional strain measures. (Default value: ThirdOrderFlag = NO).

It is possible to attach comments to the definition of the object; these comments have no effect on its definition.
