Do I have the opportunity to consider cross-sectional weakenings due to drilling or the like without having to re-model the cross-section in, for example, the DUENQ program?

Answer

If the holes are subject to a regular grid, they may be defined by the composite cross sections (Figure 1).

Otherwise it is still possible to reduce the cross section in the properties as a whole (Fig. 2).

Thus, a flat reduction of the stiffness of the cross section is made. Unfortunately, it is not possible to distinguish between reductions in the compression and tension of the cross section.

This possibility results from a reshaping of the cross-section in the DUENQ program or in some modules of the JOINTS family.
