As an example, let’s design a typical fence 7′-0″ high exposed to a wind load of 20 psf.
The first obvious step in the software is to set the backfill height to match the soil cover at the toe side. This will model a flat surface at both sides of the wall. In this example let’s set this soil cover to 1′-0″.
The fence wall will be modeled with 12 rows of 8″ wide x 8″ high concrete blocks, so that the exposed wall height is 7′-0″, as shown.
Note that the shear key dimensions have been set to zero, since it’s unlikely that a fence wall has sliding problems.
