Problem:

Why does SAM results appear to be always +ve (positive)?

Solution:

 Please see the following AutoPIPE help section: 

Help > Contents> Contents Tab> Reference Information> Analysis Considerations> Seismic Anchor Movement Analysis> The following procedure is used to obtain the SAM results.

The last step of this procedure clearly indicates why the results are always +ve (positive) for all SAM results. 

In order to include a -ve (negative) SAM case for review, create a user combination and set the scale factor for SAM load case to -1.00, as shown below
