D. Effective Footing Area (Aftg). For example, a 10-foot basement wall backfilled with a moderately soft clay soil in an undrained condition feels a load of 4,000 2. the footing area, the footing is concentrically loaded and a uniform distribution of soil pressure is assumed in design, as shown in Figure 11.4. Example Bridge.

What size footing should be used with a basement wall? Wall Footing Thickness. For masonry or concrete construction, the minimum foundation wall will be 6 inches. The minimum reinforced concrete footing thickness will be 6 inches or 1-1/2 times the length of the footing projection from the foundation wall, whichever is greater.
