Abstract:
Footings transfer loads from a structure to the soil and are designed using a two-step process. First, the footing is proportioned to keep the bearing stress below the allowable soil pressure, and then its depth and reinforcement are selected. This article presents graphical tools to simplify the first step. The presented approach has two clear advantages: its simplicity and its graphical nature.
