GGU-UNDERPIN: "Type of toe pivot" group box
In the first group box of the start dialog box of the "System/Analyse" menu item you can specify the toe pivot. This is, of course, not possible in systems without anchors or struts. In such cases, the toe is always fully fixed.
In systems with anchors or struts, a subgrade modulus for the base can be entered in place of "Toe is fully fixed" or "Toe freely pivoted". Activate the "Base is embedded" check box and enter a subgrade reaction.
