Before automating the design, it is crucial to understand the key components handled by an Excel spreadsheet analysis, as outlined in structural design guides: limitations (crucial for water-retaining structures)
When the water table is above the bottom slab, uplift can exceed the structure's weight. Add a check: Uplift force < Total weight + Soil friction . Total weight + Soil friction .
