In the STAAD.Pro V8i output file under the Job Information section, it gives a "Number of Basic Load Cases" of -2. I have noticed this before but have never been able to figure out what it is representing. I let it go until a customer circled it in a mark up. I can't seem to get this number to change. I even tried deleting all but one load case in my model and the number goes unchanged. Could someone please clarify what this number represents? I have attached a photo of the section I am referring to.
