Whenever you reset the program configuration file you must run through the error checker to get the new settings into the analysis. It is not sufficient to change the SIF multiplier and then simply re-run the analysis. Go back to the input processor now and run batch.

Even if you do this, the listed SIF in the sustained load case will still show the same value. We are not changing the SIF, we are instead modifying the SIF multiplier. You should see the difference in the calculated stress (as it relates to the bending term).
