GGU-SETTLE: Specify type of settlement analysis (Ex. 1)

With the menu item "System/Analysis options" you can specify the type of settlement to be calculated. Alternatively, you can access this menu item using function key [F6]. In principle, there are three different types:

• "Calculate settlement at given depth"
  This is usually the standard case, together with a depth of 0.0 m (= settlement at the ground level). As the area of the foundation is indeformable, the settlement at the foundation base, including for foundations with the base below the ground level, will be calculated. If a settlement depth > 0.0 is entered the settlement at this depth will be calculated.

• "Calculate settlement at layer base"
  As the layers need not necessarily be horizontally arranged, you have the possibility with this calculation method of following the influence of settlements at certain layer boundaries. To do this, activate this check box and enter the layer number.

• "Calculate settlement of a layer"
  Quite often the deformation component of an individual layer is of interest. To do this, activate this check box and enter the layer number.

• In the lower part of the dialog box, you can define a so-called influence distance. The influence of a foundation on the current settlement value will only be calculated if the distance to the foundation centre is smaller than the influence distance. If you have defined a lot of foundations the calculation time can become quite long, as, for each point at which the settlement is calculated, the influence of all foundations is considered. The influence of a foundation on the current settlement decreases with increasing distance. You can thus achieve a reduction of calculation durationusing the influence distance. A reliable statement on influence distances cannot be given, as the foundation loading also plays a large role. If you are unsure, use, as in the above dialog box, a very large value and if you are calculating a lot of foundations allow yourself a coffee during calculations.

Any calculation and presentation can be prematurely cancelled using the right mouse button.

• "With vibrodisplacement compaction"
  Activate vibrodisplacement compaction adoption after Priebe (Heinz J. Priebe, Die Bemessung von Rüttelstopfverdichtung, Ground Engineering, December 1995) using this check box.

• "Use kappa correction coefficients (DIN 4019)"
  By activating this check box the kappa correction coefficients compliant with DIN 4019 Table 1 can be adopted for settlement analysis.
