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?


If the boreholes are subjected to a regular grid, they may be defined by the combined cross-sections (Figure 1).

Otherwise, it is still possible to globally reduce the cross-section in the properties (Figure 2).

Thus, a general reduction of the stiffness of the cross-section is carried out. Unfortunately, it is thus not possible to distinguish between reductions in the compression and tension zone of the cross-section.

This possibility is obtained by reshaping the cross-section in the SHAPE-THIN program or in some JOINTS- family add-on modules in the area of the connections.
