GGU-STABILITY: Structural elements definition

In some cases, structural elements are within the slope, the shear strength of which is so great that no safety calculation is necessary, if the slip body cuts the structural element. In principle, help can be had by defining layers with high cohesion. However, it is more elegant to define the structural element as an enveloping polygon course. Structural elements have no material properties (in particular no unit weight !!!). If, however, a polygonal section of the structural element has an intersection with the currently investigated slip body, this slip body will be assigned a safety factor of 20 000.0 and no calculation will take place.

A total of 6 structural elements can be defined. The numbers in brackets on the "Element x" buttons indicate how many polygon course points each structural element contains. To define an enveloping polygon course, select the "Element 1 (0)" button, for example.

Using the "x point(s) to edit" button, define the number of polygon course points and enter the coordinates for the individual points. You do not need to close the polygon; the program does this automatically. The pen width and colour of the structural element can be edited at the top of the dialog box.
