GGU-FOOTING: Define footings (Example 1)

In the "Edit/Footing details" menu item you define the size and shape of the footing.

The "Start width", the "End width" and the "Delta width" are entered in this box. You thus define the width range to be investigated. Thus, using the example given above, the widths 0.4, 0.5, 0.6, ... to 2.0 m will be investigated.

You must also enter whether a strip or a pad footing is to be analysed. The example above would analyse a strip footing. When analysing a strip footing, enter the strip length applicable to all widths. This strip length is required for the subsequent settlement analysis.

To analyse a pad footing you define whether a constant length/width ratio (a/b) or a constant footing length (a) is analysed. If you have activated a pad footing with constant length a, you may find, for an appropriate start width, that a < b. In this case a warning message is issued to inform you that a = b.
