GGU-LATPILE: "System input" menu item

Enter the forces at the pile head for the pile you have used into a dialog box, as well as further system parameters.

You see the above dialog box if you have selected the partial safety factors in "File/New" or "Editor 1/Analysis options" menu items. The permanent and changeable loads are entered separately in accordance with the partial safety factor concept. You define both the pile length and the pile width. The width is required for determination of the spatial passive earth pressure.

The loads specified in M EBGS-Lsw 2018 can be determined for analysis of piles for noise abatement walls. In the dialog box that opens after clicking the respective button, select the required data. A dynamic wind loading factor can be defined.

If you checked the "Use absolute heights" box when defining the system, an additional entry, "Top of pile", appears in the dialog box for specifying the absolute position. In this case, all heights are measured in m AD or m site zero, i.e. the y-axis is positive upwards. You can then enter a value, for example, of 86.42 [m AD] in the "Top of pile" field. All further input must then be with reference to this value.

If the height of a previously defined system is subsequently set to absolute heights, a query follows after leaving the dialog box above asking for confirmation of whether soil strata and defined elements such as area loads, for example, should be adapted to the new pile top. Adaptation would mean that the depth of a soil layer entered as a positive value would be converted from, for example, 7.5 m to an absolute height of -7.5 m AD. If then, you only convert your system to [m AD], do not select any elements in the query box and press the "OK" button.

In the lower group box, you can define the groundwater level and a distributed load. If you are working with the partial safety factors used in DIN 1054 (new), decide whether the distributed load is "Permanent", "Changeable" or the "Component above 10.0 kN/m² changeable" (see the following dialog box). "Component above 10.0 kN/m² changeable" means, for example, that for an input of 13.5 kN/m², 10 kN/m² are adopted as permanent and 3.5 kN/m² as changeable in the analysis.
