Abstract:
Spread footings are typically designed to resist three different types of loads: gravity forces, moments, and uplift forces. Some footing designs are more complex, involving net bearing forces, uplift forces, moments, surcharge loads, and “passive” resistance from cantilevering slabs on ground. This article presents a procedure that allows designers to account for all of these design loads in their analysis and view the results in an interaction diagram.
