Hi Phil,
I do not know how to calculate that either. I just wanted to say there are a few pages in the "the collected works of Stan Hall" that
touch a little on static load testing and calculating the forces. Pressures at given speeds per area.
I know the final test is sand bags. Calculating the minimal amount of material to do the job is what I personally do not know either.
I'm sure there are some pretty sophisticated software programs out there that do this.
