I am analyzing an existing structure. I have spread footings under frame columns. I have accounted for the self weight of the footing in my design, I strategically have not accounted for a surcharge. I have calculated the OSF and net uplift per the technical notes, and have been able to recreate the same values.
1. Why is the uplift value only reported in some of the 'Spread Footing Design' reports for my frame columns, but not all?
2. I am getting this error on my frame columns even when my OSF > 1.0, why would this be?
