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

Answer

If the holes are subject to a regular grid, they can be defined using the composite cross-sections (see Fig. 01).

Otherwise, there is still the possibility to reduce the cross-section in the 'Properties' (see Fig. 02). This results in a general reduction in the stiffness of the cross-section. Unfortunately, it is not possible to distinguish between reductions in the compression and tension areas of the cross-section. This option only exists if the cross-section is redesigned in the SHAPE-THIN program or using some modules of the JOINTS family in the area of the connections.
