GGU-SETTLE: Program concept

In order to calculate foundation settlements, input of the constrained modulus profile is necessary, as well as the foundation data (width, length, foundation stress). Many comparable programs define this constrained modulus per foundation. The GGU-SETTLE program takes a different, much more flexible path. The constrained modulus profiles are defined in a triangle mesh. At the nodes of this triangle mesh you can edit the thickness of the layers involved. After having defined the triangle mesh you can place the foundations within this mesh. During the following calculations the program determines the valid constrained modulus profile from linear interpolation within the triangle concerned. Even after calculations are complete, or after placing the foundations, the triangle mesh can be edited or supplemented.

In order to secure a sensible interpolation within the constrained modulus profile mesh, it is necessary for all nodes to have the same number of layers, and for all layers to have the same constrained modulus within the mesh. The thickness of the layers, however, can be varied. If your system has areas in which certain soil layers are not present (e.g. peat lenses only in certain areas), then simply assign these layers a thickness of '0' at the appropriate nodes.

As, from personal experience, the reading of user manuals is a chore, there will now follow a short description of the main program functions using the following worked examples. After studying these sections you will be in a position to carry out calculations with the GGU-SETTLE program. You can take the details of the program from the following chapters.
